Answers
To find the length of the missing side x, use Tan trigonometric formula
Tan: [tex]\frac{opposite}{Adjacent}[/tex]
Tan 21 = [tex]\frac{10.5}{x}[/tex]
Tan 21 × [tex]\frac{1}{10.5}[/tex] = [tex]\frac{10.5}{x}[/tex]×[tex]\frac{1}{10.5}[/tex]
[tex]\frac{10.5}{Tan 21}=x[/tex]
x=27.4
X= 27.4 ft
Hope it helps!
Answer:
x = 27.4 ft
Step-by-step explanation:
Here given:
opposite side: 10.5 ftadjacent side: x ftto that angle: 21°So, use tan rule:
[tex]\sf tan(\theta) = \dfrac{opposite}{adjacent}[/tex]
insert values
[tex]\sf tan(21) = \dfrac{10.5}{x}[/tex]
make 'x' subject
[tex]\sf x= \dfrac{10.5}{tan(21) }[/tex]

Step-by-step explanation:
You roll a fair six-sided die twice. Find the probability of rolling a 2 the first time and a number greater than 4 the second time.
Answers
Answer:
1/18
Step-by-step explanation:
So to find the probability of two independent events, you simply multiply the two probabilities. So the probability of rolling any individual number is 1/6 because there's 6 possibilities, and there are no duplicate numbers. So the probability of rolling a 2 the first time is 1/6. The probability of rolling a number greater than 4 has a probability of 2/6, since the numbers 5 and 6 are both greater than 4. This can be further simplified to 1/3. Multiplying these two probabilities gives you 1/18

find x and y !!!!
pls pls help
Answers
Answer:
x = 59°, y = 31°
Explanation:
Angles (x) and (x - 28) sum ups to 90° on a straight line.
→ x + (x - 28) = 90
→ 2x - 28 = 90
→ 2x = 90 + 28
→ 2x = 118
→ x = 59°
Then find value of y
Angle y, x, 90° lies on a straight line which sum ups to 180°
→ x + y + 90° = 180°
→ 59 + y + 90° = 180°
→ y = 180° - 149°
→ y = 31°

ABC is a right-angled triangle.

Calculate the length of AB. Give your answer correct to 2 decimal places.
The picture is also attached below.
The length of the side AB is 9.85 cm.
From the triangle, it is given that
b= AC=16 cm
∠C=38°
Given that ΔABC is a right-angled triangle.
where ∠B=90°
So, here we can apply the SOH CAH TOA identity
As we know the value of sinθ is the ratio of the opposite side and the hypotenuse of the angle θ.
So, sinθ = opposite side/ hypotenuse
In triangle ΔABC
⇒ sin 38°= AB/AC
⇒ sin 38°= AB/16
⇒ AB= 16 sin 38°
⇒ AB= 9.85 cm
Therefore the length of the side AB is 9.85 cm.

Answer:
x = 65 , y = 64
Step-by-step explanation:
y - 16 and 2y + 4 are same- side interior angles and sum to 180° , that is
y - 16 + 2y + 4 = 180
3y - 12 = 180 ( add 12 to both sides )
3y = 192 ( divide both sides by 3 )
y = 64
then
2y + 4 = 2(64) + 4 = 128 + 4 = 132
the exterior angle of a triangle is equal to the sum of the 2 opposite interior angles.
2y + 4 is an exterior angle of the triangle , then
x + 67 = 132 ( subtract 67 from both sides )
