Answer:

The answer for the first picture is 84

The answer for the second picture is 36

Step-by-step explanation:

The first triangle is a isosceles triangle which means that two angle lengths must be the same. We use the only angle measurement  which is 48 and subtract it from 180 twice because there are two angles lengths that are the same, once we subtract from 180 we have 84. The same process is followed for the second triangle.

180-48-48=84

Second Triangle:

180-72-72=36

Answer:

The first angle is 84

The second angle is 36

Step-by-step explanation:

The two sides are the same length, so it is an isosceles triangle.

The sides are the same so the angles at the base are the same

The three angles of a triangle add to 180 degrees

48+48+x = 180

Combine like terms

96+x= 180

Subtract 96 from each side

96-96+x= 180-96

x =84

The unknown angle is 84

The two sides are the same length, so it is an isosceles triangle.

The sides are the same so the angles at the base are the same

The three angles of a triangle add to 180 degrees

72+72+x = 180

Combine like terms

144+x= 180

Subtract 144 from each side

144-144+x= 180-144

x =36

The unknown angle is 36
