Answer:
Alternate exterior angles are congruent. So, set the angles equal to each other and solve for x.
2x + 50 = x + 76
x = 26
So, ∠2 = 2x + 50 = 2(26) + 50 = 102°
Step-by-step explanation:
Answer is D because 29 deg and 61 deg add up to 90 degree.
Multiply 45 by 2/3 2/3 = 0.66666 so 45*0.6666 = 30
<span>7a+(4+5a)=12a+4
The first step to this is to simplify both sides of the equation.
</span><span>You have to combine all of the like terms first...
(7x + 5x) + (4) = 12x + 4
12x + 4 = 12x + 4
Now the second step is to subtract 12x from both sides....
</span>12x + 4 = 12x + 4
-12x -12x
4 = 4
Now you will subtract four from both sides and get....
0=0
