The answer is 90, Because angle D is a 90 degree angle, and 180- 90=90, so the answer is 90.
Let x is Jiri's age
2x is Pamela's age
x + 2x = 33
3x =33
x = 33/3
x =11
Answer: Jiri's age is 11
The slope is 7/8.
Slope formula is the change in y over the change in x,
M=y2-y1 / x2-x1
M= -3 - (-10) / -2 - (-10)
Remember that two negatives equal a positive.
That makes the equation:
M= -3 + 10 / -2 + 10
M= 7/8
