The measures of two angles of a triangle are 35° and 45°. What is the measure of the third angle of the triangle
2 answers:
Answer:
The third angle is 100 degrees.
Step-by-step explanation:
The three angles of a triangle add to 180 degrees.
Lets call the third angle x
x+35+45 = 180
Combine like terms
x +80 = 180
Subtract 80 from each side
x+80-80 = 180 - 80
x = 100
The third angle is 100 degrees.
Answer:
100°
Step-by-step explanation:
triangles always add up to 180 degrees
First add 35 and 45
35+ 45 = 80
Then subtract 80 from 180
180-80 =100

Yes but at the same time you have to look for the range and domain
Answer:
60 + .20*120= 84
10 + 120/10*.10= 11.20
90 - 60 + 30/.20 = 180
