Given ∆ABC≅∆DEF, m∠A=5x+12 and m∠D=8x, find m∠A and m∠D.
1 answer:
Given :
Two triangle ∆ABC and ∆DEF are congruent.
m∠A=5x+12 and m∠D=8x.
To Find :
m∠A and m∠D.
Solution :
Since, both the triangle are congruent.
m∠A = m∠D
5x + 12 = 8x
3x = 12
x = 4
m∠A = 5(4) + 12 = 32°
m∠D = 8(4) = 32°
Therefore, value of m∠A and m∠D is 32°.

Answer:
5x² - 31x + 30
Step-by-step explanation:
(5 - x)(6 - 5x)
= 30 - 25x - 6x + 5x²
= 30 - 31x + 5x²
= 5x² - 31x + 30
The answer is 24 root 3 or 41.56921938.
