Need help find the measures

Step-by-step explanation:

The sum of angles that make up a linear angle is 180°, so we have ...

  60 + a + 55 = 180

  a = 65 . . . . . . . . . . . . . . subtract 115

The acute angles in a right triangle are complementary, so we have ...

  b = 90 -65 = 25

Vertical angles are congruent, so ...

  c = b = 25

___

Angle d is the complement of the one marked 15, so its measure is ...

  d = 90 -15 = 75

The angle measures are ...

  a = 65°

  b = 25°

  c = 25°

  d = 75°

a = 65

b = 25

c = 25

d = 75

hope it's helpful

b

step-by-step explanation:

question 1 is 8, question 2 is 9, question 3 is 24

step-by-step explanation:

now, the numbers they give you at the top are the key. from there, you just have to plug and chug! let's try 1, 2, and 3!

key: a=3, b=5, c=6

1. a+5

remember, a=3, so we plug that in to get 3+5=8

2. 15-c

c=6, so we plug that in to get 15-6=9

3. 4b

b=6, so we plug it in to get 4*6=24

time to try the rest on your own! if you put the answers below in a comment, i'll check them for you!
