Answer:
Y = 32.7°
Step-by-step explanation:
We will apply the Cosine law in the given triangle XYZ,
x = 90 ft
y = 55 ft
z = 50 ft
We have to find the measure of angle Y.
y² = x² + z² - 2xzCosY
(55)² = (90)² + (50)² - 2(90)(50)cosY
3025 = 8100 + 2500 - 9000.cosY
9000.cosY = 10600 - 3025
cosY =
= 0.84167
Y =
Y = 32.68 ≈ 32.7°
Therefore, measure of angle Y = 32.7°

<h2>Answer:</h2>
The value of t is:
t=48.8889
<h2>Step-by-step explanation:</h2>We are asked to solve the linear equation in terms of variable t.
The equation is given by:
Firstly we will solve the parentheses term in the left and right hand side of the equality as follows:
Now we combine the like terms on the left side of equality by:
Now we subtract both side of the equation by 5 to get:
Now on dividing both side of the equation by 0.90 we get:
Hence, the value of t is: 48.8889
