Answer:
∠U = 40°
Step-by-step explanation:
in order to find the missing angle of U we need to know the two other angles.
We know that ∠T is 65° and we know that ∠TSF is 105°. Because ∠TSF is an exterior angle, we can subtract 180 to get the interior angle. This would mean that ∠S is 75°.
Using this we can add 65 to 75 then subtract the total from 180 to get ∠U.
This would mean that ∠U is 40°
the answer for x is 7.27 recurring
Answer:
We can write sin 21° as 1200 / x and also 0.36 so we can write:
1200 / x = 0.36
1200 = 0.36x
x = 1200 / 0.36
x ≈ 3333 ft
Y = 3x + 15
y = 2x + 8
3x + 15 = 2x + 8
-2x -2x
——————-
x + 15 = 8
-15 -15
—————-
x = -7
