56° and 34°
complementary angles sum to 90° thus
3x - 10 + 2x - 10 = 90
5x - 20 = 90
add 20 to both sides of the equation
5x = 90 + 20 = 110
divide both sides by 5
x = = 22
angle 2x - 10 = (2 × 22) - 10 = 44 - 10 = 34° and
angle 3x - 10 = (3 × 22) - 10 = 66 - 10 = 56°
Answer:
75/4 = 18.75
Step-by-step explanation:
Because a squar is 4 sides add 75 is the perimiter
Answer:
no
Step-by-step explanation:
SAS stands for side angle side. so in this question we know that one side is equal to another side, but we don't know wether or not there is another angle and another side that is congruent. so for that reason it is not congruent by SAS.
C. multiplication (the 8 x 9 within the parenthesis)
Answer:
1/3
Step-by-step explanation:
(7-2)/(17-2)=5/15=1/3
