Answer:
Let ABC be a triangle such that CA is produced to meet at E.
We know, an exterior angle of a Triangle is equal to non- adjacent interior angle, so
8x - 10 = x + 15 + 2x + 20
or, 8x - 3x = 35 + 10
or, 5x = 45
or, x = 9
the value of x is 2.
Step-by-step explanation:
5(3x - 4) = 2(2x + 1)
15x - 20 = 4x + 2
15x - 4x = 2 + 20
11x = 22
x = 22/11
x = 2
5/8
1/4 (2/2)=2/8
3/8 (already simplified)
2/8+3/8=5/8
Step-by-step explanation: This is the answer
