i rlly need help; finding angles

Answers

Answer 1

Answer:

1=35 find angle 2 80+65-180=35

2= 65 vertical angles are congruent ex 115-180

3=29 ex. 90+65-180=29

4= 115 vertical angle congruent

5=65 vertical angles are congruent ex 115-180

6=65 35+80-180=65

7=144

Answer 2

Answer:

∠1 = 35 ; ∠2 = 65 ; ∠3 = 29 ; ∠4 = 115

∠5 = 65 ; ∠6 = 36 ; ∠7 = 144

Step-by-step explanation:

∠4 = 115 {Vertically opposite angles}

∠5 + 115 = 180 {linear pair}

∠5 = 180 - 115

∠5 = 65

∠2 = ∠5 {Vertically opposite angles}

∠2 = 65

∠1 + 80 +∠2 = 180 {Angle sum property of triangle}

∠1 + 80 + 65=180

∠1 + 145 = 180

∠1 = 180 - 145

∠1 = 35

∠5 + ∠7 + 90 + 61 = 360 {angle sum property of quadrilateral}

65 + ∠ 7 + 90 + 61 = 360

∠7 + 216 = 360

∠7 = 360 - 216

∠7 = 144

∠6 + ∠ 7 = 180 {linear pair}

∠6 + 144 = 180

∠6 = 180 - 144

∠6 = 36

∠3 + ∠4 +∠ 6 = 180 {angle sum property of triangle}

∠3 + 115 + 36 = 180

∠3 + 151 = 180

∠3 = 180 - 151

∠3 = 29

A retailer was given a trade discount are 15% and cash discount of 6% by the wholesaler. How much did the retailer pay for a good marked price for $3745

Answers

Answer: $2992.26

===================================================

Explanation:

If you're given a 15% discount, then you still have to pay the remaining 85% (because 100% - 15% = 85%)

Rewrite 85% into 0.85

The multiplier for "15% discount" is 0.85

Similarly, the multiplier for a 6% discount is 0.94; note how 100% - 6% = 94% = 0.94

When we have multiple discounts chained together like this we find the product of the multipliers. So we multiply the 0.85 and 0.94 to get

0.85*0.94 = 0.799

After chaining together the two discounts, you will have to pay 79.9% of the original value. This means the overall discount is 20.1%

Take the result of 0.799 and multiply that with the marketed price of $3745 to get the final answer

0.799*3745 = 2,992.255 which rounds to 2,992.26

Write an equation passing through the point and parallel to the given line

(4,7); y = 3x + 6

Thank you!

Answers

Answer:

Step-by-step explanation:

y=3x+6

slope is 3, so y=3x+[unknown].

We insert the point (4,7) into the equation.

7=3*4+[unknown]

7=12+[-5]

so the answer is

y=3x-5

Answer:

y = 3x - 5

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

y = 3x + 6 ← is in slope- intercept form

with slope m = 3

Parallel lines have equal slopes, thus

y = 3x + c ← is the partial equation

To find c substitute (4, 7) into the partial equation

7 = 12 + c ⇒ c = 7 - 12 = - 5

y = 3x - 5 ← equation of parallel line

In triangle XYZ, m∠Z > m∠X + m∠Y. Which must be true about △XYZ?

m∠X + m∠Z 90°
∠X and∠Y are complementary
m∠X + m∠Y < 90°

Answers

Answer:

m < X + m < Y < 90

Step-by-step explanation:

For the triangle XYZ, m∠Z > m∠X + m∠Y we see that because the total internal angles of a triangle is 180,m∠X + m∠Y < 90° is a true assertion

Option C is correct

What must be true about triangle XYZ?

Generally, A triangle's major feature is its total internal angles as 180

Therefore

if m∠Z > m∠X + m∠Y this means that m<z must be greater than 90 degrees

This goes to show us that

m<X + m<Y < 90 because as we earlier mentioned the total internal angles of a triangle is 180 .

In conclusion, For the triangle XYZ

m∠X + m∠Y < 90° is a true assertion

I don't know if my answer is correct!!! plzz help asap

Answers

Answer:

102 degrees

Step-by-step explanation:

m< CDA & m<CBA are both 78 degrees because they are both acute angles.

m<DAB & m<DCB are both 102 degrees because they are both obtuse angles.

Whenever you add 78 + 78 + 102 + 102 you get 360 degrees which is how much a four-sided figure should be.

Hope this helps!

Answer:

∠ DAB = 102°

Step-by-step explanation:

The consecutive angles of a parallelogram are supplementary.

∠ CDA and ∠ DAB are consecutive angles, then

∠ DAB = 180° - 78° = 102°
