I don't know what to do.

the measure of all the angles within a triangle is = 180 degrees.

the two given angle measures are 70 and 90.

90+70= 160 making the remaining angle = 20 degrees

the two triangles are similar to each other, so they have the same angle measurements. making the measure of angle 1 = 20 degrees

7

step-by-step explanation:

yuo ned the activity or vertical angle of the form of 1,7 but 2,2 has a c4,2 as it verticie so i not have a car

$25

step-by-step explanation:

25 - 4.50 = 20.5

20.5 / 2 = 10.25

10.25 + 10 = 20.25

20.25 - 12.50 = 7.75

therefore the answer is $25 as shown as the first number.
