To convert a mixed fraction into a first you need to convert it into an improper fraction.
To do that multiple 87 to 25 and then add 24
If you do that you will get 2199/25
then divide the numerator by the denominator.
87.96 is what you will get if you divdie it correctly
Answer:
E
because both sides are equal when substituted by 3 & 5
Answer: 115°
Step-by-step explanation:
We should note that the sum of the angles that are in a triangle is equal to 180°, therefore we will add the angles given and equate them to 180°. This will be:
(8x - 5) + (2x) + (3x - 10) = 180
8x - 5 + 2x + 3x - 10 = 180
Collect like terms
8x + 2x + 3x = 180 + 5 + 10
13x = 195
x = 195/13
x = 15
The angles are:
8x - 5 = 8(15) - 5 = 120 - 5 = 115°
2x = 2(15) = 30°
3x - 10 = 3(15) - 10 = 45 - 10 = 35°
Therefore, the largest angle is 115°
Yes, since the other two numbers on each side are the same, any number can fit well in this equation.
