-2x+x-4=-7 , -1x=-3, x=3. y=3-4, y=-1
Part A
The small red arcs indicate that angles PQS and RQS are congruent.
13x - 1 = 2(6x + 4)
13x - 1 = 12x + 8
x = 9
m<PQR = 13x - 1 = 116
m<RQS = 6x + 4 = 6(9) + 4 = 58
m<PQS = 116 - 58 = 58
Part B
12^2 + (OH)^2 = 13^2
144 + (OH)^2 = 169
(OH)^2 = 25
OH = 5
r = OH = 5
Part C
WZ/ZY = WX/XY
24/12 = 30/XY
2 = 30/XY
2(XY) = 30
XY = 15
You can use the pythagorean theorem. Make sure that you put the measurements in the right places though. Since 11 is the measure of the hypotenuse, 11 has to be c. When you plug in the information that you have, it should look like this:
8^2 + b^2 = 11^2
Square 8 and 11.
64 + b^2 = 121
Subtract 64 from 121
121 - 64 = 57
The new equation is:
b^2 = 57
Now take the square root of both sides to get b by itself.
b = about 7.5
Answer: The height of the triangle is 7.5

Answer:
-12.75
Step-by-step explanation:
Find the product of 51 and -2.5. Use the distributive property to rewrite and solve.
The next step using Distributive property is to expand the brackets
5.1 × 2.5
Step 1: Distributive property
51(-2.0) + 51(-0.5)
Step 2: Expand the brackets
-10.2 + -2.55
Step 3
- 12.75
Answer:
The answer is A) x equals 3
