If the measures of two angles of a triangle are 92 degrees and 19 degrees, what is the measure of the third angle?
2 answers:
Answer:
69
Step-by-step explanation:
92+19=111
180-111=69
every triangle has three angles that add up to 180, so if you add the two you already have and subtract that number from 180 you will get the third angle
Answer:
69 deg
Step-by-step explanation:
The sum of the measures of the angles of a triangle is 180 deg.
m<1 + m<2 + m<3 = 180
92 + 19 + m<3 = 180
11 + m<3 = 180
m<3 = 180 - 111
m<3 = 69
Answer: 69 deg
