Answer 1

Answer:

m<ABC=94°

m<BCD=25°

m<ACB=43°

Step-by-step explanation:

To find <mBCD

m<ABD=133°, so m<CBD=133° too.

A triangle is equal to 180°.

22°+133°=155°

80°-155°=25°

To find <mACB

You first need to know triangle ACD measurements.

m<ADC=44° (22°+22°)

Then you take the two 25 and add them.

25°+25°=50°

50°+44°=94°

180°-94°=86°

86°÷2=43°

To find m<ABC

43°+43°=86°

180°-86°=94°
