Answer:
35
Step-by-step explanation:
Since this triangle is a 90 degree angle, all you'd have to do is subtract 55 from 90 and you've got you answer.
I got A, -32, but it has been awhile since I have learned this in my math class. You might want to wait for someone else to verify this answer.
Answer:
x= 2
Step-by-step explanation:
Given that,
AB = 7.5x
BC = 6x+3
AC = 10x-5
ΔABC is an equilateral triangle.For an equilateral triangle, all sides are equal. ATQ,
AC = BC = AB
10x-5 = 6x+3
Taking like terms together
10x-6x = 5+3
4x = 8
x = 2
Hence, the value of x is equal to 2.
You multiply fractions simply by multiplying numerators and denominators with each other:
