Directions: Solve For X, Then Find Each Angle Measure.

Answers

Answer 1
(5x - 2) + (11x - 21) + (9x + 3) = 180
all angles must equal 180

gather like terms
25x + 20 = 180
+20 +20
25x = 200
/25 /25

x = 8

angle d = 38
angle e = 75
angle f = 67

Answer 2

The sum of all three interior angles of a triangle is 180° thus the measure of x for the given triangle is 8 therefore,∠E = 75°,∠D = 38°, and ∠F = 67°.

What is a triangle?

A triangle is a 3-sided shape that is occasionally referred to as a triangle. There are three sides and three angles in every triangle, some of which may be the same.

It is known that the sum of all three angles inside a triangle will be 180°.

Therefore, ∠E + ∠F + ∠D = 180°.

Given that, ∠E = 9x + 3,∠F = 11x -21 and  ∠D = 5x - 2

So, 9x + 3 + 11x - 21 + 5x - 2 = 180

25x - 20 =180

25x = 200

x = 8

So,

∠E = 9(8) + 3 = 75°

∠F  = 11(8) - 21 = 67°

∠D = 5(8) -2 = 38°

Hence "The sum of all three interior angles of a triangle is 180° thus the measure of x for the given triangle is 8 therefore,∠E = 75°,∠D = 38°, and ∠F = 67°".

the sum of three numbers is 131. the third number is 4 times the first. the second number is 5 more than the first. what are the numbers

Answers

Step-by-step explanation:

let the numbers are:

a, b, and c

the equation would be:

a+b+c = 131

c = 4a

b = a+5

=>

a + a+5 +4a = 131

6a +5 = 131

6a = 131-5

6a = 126

a= 126/6

a = 21

b = a+5 = 21+5

b = 26

c = 4a = 4(21)

c = 84

A plane travels 800 metres along the runway before taking off at an angle of 10∘

I hope this step by step explanation helps.

A plane travels 800 meters along the runway before taking off, then the distance travelled from the starting point will be equal to 1793.24 meters.

What is Velocity?

Velocity is the rate at which a moving object's direction changes as perceived from a certain vantage point and measured by a particular unit of time. Kinematics, the area of special relativity that investigates how bodies move, starts with the fundamental idea of speed.

In order to be explained, the scientific vector quantity known as velocity needs to have both a magnitude and a direction.

As per the given data in the question,

Distance travelled by plane = 800 meters

Use the equation,

a² = b² + c² -2bc cos A

d² = 800² + 1000² - (2 × 800 × 1000 × cos 170°)

d² = 1640000 - 1600000(cos 170°)

d² = 3215692.405

d = 1793.24
