90% of 130 is 117 because 10% is 13 and 13x9 is 117 so that is part a. 130-117 is 13 so that is part b. And part c is correct because 100%-90%=10%. I hope this is helpful.
Slope is 0 , y intercept is 1 the answer is j x
Answer:
14
Step-by-step explanation:
Knowing the first triangle is isosceles, and given the degree is 69.
We can find the top left angle as 180-69-69=42
42 combine with another angle to make a right angle
90-42=48.
The second triangle is also isosceles, so to find 2
we can use 180-42=138 (supplementary angles rule)
and given 10x-8=138
10x=140
x=14
