Answer:
∠MEJ=25°
Step-by-step explanation:
step 1
Find the value of x
we know that
arc LJ+arc KM+arc KL+arc MJ=360° ----> complete circle
substitute the values
(4x+50)°+6x°+(x+10)°+4x°=360°
solve for x
(15x+60)°=360°
x=300°/15=20°
step 2
Find the measure of angle MEJ
we know that
The measurement of the external angle is the semi-difference of the arcs which comprises
∠MEJ=(1/2)[arc MJ-arc KL]
arc MJ=4(20°)=80°
arc KL=20°+10°=30°
substitute the values
∠MEJ=(1/2)[80°-30°]=25°
We can use the points (10, -11) and (10, -2).
Slope formula: y2-y1/x2-x1
= -2-(-11)/10-10
= 13/0
Since the denominator is 0, the slope is undefined.
Best of Luck!
The answer is C and D
First we must make one side of the equation zero, so we subtract 7 on both sides of the equation, making the equation 9x^2 - 6x - 6 = 0
Then we will use the quadratic formula to find the answers.
using the Quadratic Formula where:
a = 9, b = -6, and c = -6
and the formula is 6 +- ![\sqrt{6^{2} } -4 (9)(6) /2 (9)](https://tex.z-dn.net/?f=%5Csqrt%7B6%5E%7B2%7D%20%7D%20-4%20%289%29%286%29%20%2F2%20%289%29)
