I really need help my grade keeps dropping bc I don’t understand these

Step-by-step explanation:

measure of angle y is 90 degrees

measure of angle z is 70 degrees

this will be solved by angle sum property which states that the sum of all the interior angles of a triangle is 180

so 90+70+ angle 1=180

160+angle 1=180

angle 1=180-160

angle 1 =20degrees

2 and 1.

step-by-step explanation:

plug in each answer. 0 doesn't work, 1 does. so does 2. 4 doesn't:

0 = 1 is not true.

2 = 2 is true.

4 = 4 is true.

8 = 16 is not true.

hope this !
