Answer:
12.5%
Step-by-step explanation:
% increase = (new value - initial value)/initial value x 100
= (90-80)/80 x 100
=10/80 x 100
= 12.5%
Remember that a percentage means "parts out of 100". 24% in decimal form is therefore 0.24, because it is 24 out of the possible 100, or 1.0. To find 24% of 75, you just multiply 0.24 times 75:
75 x 0.24 = 18
To find the measure of angle 1, you add 33 and 57
That would equal 90
Since all triangles equal 180, you would subtract 90 from 180
So the answer would be 90.
Answer:
so basically you have to multiply all the numbers and divide by 2 and the rest is self explanatory
