Need to find missing angles pls me i can’t do it

∠d and ∠132°, ∠a and ∠90°, ∠c and ∠138° are supplementary angles.

The sum of measures the two supplementary angles is 180°. Therefore

m∠a = 180° - 90° = 90°

m∠c = 180° - 138° - 42°

m∠d = 180° - 132° = 48°

∠b and 90°, ∠e and 132° are vertical angles.

Vertical angles are equal. Therefore

m∠b = 90°

m∠e = 132°

the equation cos(35) =a/25 can be used to find the length of bc what is the length of bc? round to the nearest tenth

step-by-step explanation:

look at the picture.

y-intercept for the function on a picture is 4 → point (0, 4).

y-intercept for the function

is for x = 0. substitute:

y-intercept is 8 → point (0, 8).
