Answer:
8
Step-by-step explanation:
x+x+7=23
2x=16
x=8
If the point (a, b) is in Quadrant IV of a coordinate plane, then the x-coordinate of (a, b) will be positive and the y-coordinate will be negative.
EX: (5, -5)
Let the length of the diameter be d and radius be r, thus to solve for d we proceed as follows:
r²+31²=(r+15)²
solving for d we solve for r
r²+961=r²+30r+225
putting like terms together we obtain:
r²-r²+961-225=30r
736=30r
solving for r
r=24.53
thus
d=24.5333×2
d=49.067~49.1
Answer is D. 49.1
Answer:
x = 9.99
Step-by-step explanation:
Using sine law , we have
Sine F/f = sine E/x
Sine 55deg/12 = Sine43deg/x
0.8192/12 = 0.6820/x
Cross multiply
0.8192 X x = 12 x 0.6820
0.8192x = 8.184
Divide both sides by 0.8192
0.8192x/0.8192=8.184/0.8192
x = 9.99
