Something that you should remember is that the sum of the angles of a triangle add up to 180°.
Since we are given 100° and that the other two angles are equal, we can set up an equation like this:
, where x is the 2 angles.
Doing the math, the measure of each unknown angles is 40°.
Answer:
76%
Step-by-step explanation:
Do turn decimals into percentages you just gotta multiply by 100.
0.76×100=76
Answer:
Radius is 2 centimeters
Step-by-step explanation:
<u>4π is the area of a circle</u>
<u>Area of a circle = πr^2</u>
4π / π = πr^2 / π
sqrt(4) = sqrt(r^2)
2 = r
Answer: Radius is 2 centimeters
Answer:
90 degree's
Step-by-step explanation:
Two angles are called complementary when their measures add to 90 degrees. Two angles are called supplementary when their measures add up to 180 degrees
Answer:
x is all real numbers
Step-by-step explanation:
2(y-6)=3(y-4)-y
Distribute
2y - 12 = 3y-12 -y
Combine like terms
2y -12 = 2y -12
Subtract 2y from each side
2y-12-2y = 2y-12 -2y
-12 =-12
This is always true so there are infinite solutions
x is all real numbers
