The total amount of degrees in a triangle is 180. All three angles should add up to 180˚
We know that 40+60 = 100
The next step is to do 180-100 to get the other angle.
180-100 = 80
So the measure of the third angle is 80˚
Hope this helps!
(Also if you want to do this in one equation, you would do 40+60+x = 180
40+60+x = 180
100+x = 180 (combine like terms)
x = 80 (Subtract 100 from both sides)
Answer:
you need to simplify them like 2n+6 simplifird if 2.(n+3)
Step-by-step explanation:
Formula for trapezoid area is A=b1+b2 x heightx 1/2 so your answer would be 161m squared
60/100 / 60 are shaded out of the hundred. Simplified would be 3/5. The decimal would be 0.6.
