Are they asking for the surface area?
Answer:
The measures of the angles are 150° and 30°.
Step-by-step explanation:
Let x and y represent the measures of the angles, with x representing the larger angle.
x + y = 180 . . . . . . the two angles are supplementary
x = 90 + 2y . . . . . one is 90° more than twice the other
___
Substituting the expression given by the second equation into the first, we have ...
(90 +2y) +y = 180
3y = 90 . . . . . . . . . . collect terms, subtract 90
y = 30 . . . . . . . . . . . divide by the coefficient of y
x = 180 -y = 150
The measures of the angles are 150° and 30°.
The pythagorean theorem states that for any RIGHT-ANGLED TRIANGLE, the relationship between the side lengths are A²+B²=C², where C is the hypotenuse :P
Which means that it can only be applied on right angled triangles~
So your answer would be B, a right-angled triangle.
Ask me if you are unsure about anything <3
Answer:
55%
If 1,210 people would buy that type of car again, they were satisfied with it.
The fraction of people who were satisfied would be .
To find a percentage, we need to divide the top of the fraction by the bottom, then multiply by 100.
1210/2200 is equal to 0.55. This is the decimal form of the fraction, but we need the percentage.
0.55 x 100 is equal to 55.
The answer is 55%
