Answer:
r=5
Step-by-step explanation:
r+2=7
r=5
The 2 triangles are congruent therefore
9x-1 = 10x-10
x= 9
so 80* 2 = 160
angle cad measures 160 degrees
PQ peependicular to PS
Thus angle QPS = 90⁰
7x - 9 + 4x + 22 = 90⁰
11x = 77
x = 7
Thus angle QPR = 7(7) - 9 = 40⁰
Answer:
It is the parabola x^2 moved to the right. So 3rd option.

Answer:
about 15.6cm.
Step-by-step explanation:
I got my answer of 15.6cm because I did the Pythagorean theorem.
a^2+b^2=c^2
The values of "a" and "b" are the legs of the triangle, and the value of "c" is the hypotenuse. So, the equation with the values given is 9^2+b^2=18^2.
Simplified is 81+b^2=324. Next, you have to subtracted 81 on each side, so you have "b" by itself. b^2=243. Now, I know that b^2= 243. Next, find the square root of 243. The square root of 243 is 15.58845727. This value rounded to the nearest tenth is about 15.6.
In conclusion, the measure of the other leg is about 15.6cm.
