Answer:
Step-by-step explanation:
first, you have to recognize that the two angles will be the same. They are like that b/c of how they are opposites. next , b/c they are the same , set them equal to each other and then solve the equation for x ( isolate x)
29 = 4x -1
29 + 1 = 4x -1 + 1
30 = 4x
30/4 = 4x /4
7.5 = x
now to find ∠DCE just plug in x, but you also can just observe that ∠DCE is going to be 29° b/c the angle opposite of it is also.
Answer:
x = sqrt(147)
Step-by-step explanation:
This is a right triangle, so we can use the Pythagorean theorem.
a^2 + b^2 = c^2 where a and b are the legs and c is the hypotenuse.
x^2 +7^2 = 14^2
x^2 +49 = 196
Subtract 49 from each side
x^2 = 147
Take the square root of each side
sqrt(x^2) = sqrt(147)
x = sqrt(147)
