Step-by-step explanation:
You have to multiply by converting the second fraction into upside down :
Answer:
The angles in the triangle and 10, 80 and 90
Step-by-step explanation:
The two angles that are left in a right triangle add to 90 degrees
8:1 means that there total is 9
8x+1x = 9x
9x = 90
Divide by 9
9x/9 = 90/9
x = 10
8*10 = 80
1*10 = 10
The angles are 80 and 10
The angles in the triangle and 10, 80 and 90
We know that these two angles are equal to each other (There is the "congruent" sign) so we can set them equal to each other and solve for x
3x - 17 = 25 - 3x
(3x + 3x) - 17 = 25 + (-3x + 3x)
6x + (- 17 + 17) = 25 + 17
6x/6 = 42/6
x = 7
Hope this helped!
This is equal to...
We want "x" so we need to isolate it using laws of exponents...
because
because
x = 4
