Answer:
x = 12
Step-by-step explanation:
Triangle DGH is isosceles with base angles at D and G. The external angle 134° at H is the sum of those two base angles, so we have ...
2(5x+7) = 134
5x +7 = 67 . . . . . divide by 2
5x = 60 . . . . . . . subtract 7
x = 12 . . . . . . . . divide by 5
Answer:
The second one, my order is different, but they are equivalent answers
Step-by-step explanation: 6 22 22 18
(√6 + √11) / (√5 +√3) multiple top and by (√5 - √3) note the minus
(√6 + √11) × (√5 - √3) / (√5 +√3) x (√5 - √3)
(√30 + √55 - √18 - √33) / (5 - 3)
(√30 + √55 - 3√2 - √33) / 2
Step-by-step explanation:
abx² - (a⁴ + b⁴)x + (a³b³) = 0
(ax - b³)(bx - a³) = 0
Therefore x = b³/a or x = a³/b.
Given that DH=4x-2 and FH=x+28, the value of x which will make DEFG a parallelogram will be given as follows;
4x-2=x+28
4x-x=28+2
3x=30
thus
x=30/3
x=10
The answer is C] 10
