45 degrees because a triangle is 180 degrees all around, and if u have a 90 degree angle and 45 degree angle you would add the two angles given then subtract from 180 degrees.

Answer:

$\frac{(3-2a)}{a^2}$

Step-by-step explanation:

Given expression is,

$\frac{3}{a^2}- \frac{2}{a}$

First equalize the denominators of the fractions,

$\frac{3}{a^2}-\frac{2a}{a^2}$

Now combine the fraction as a single fraction,

$\frac{(3-2a)}{a^2}$

Since, we can not solve this fraction further, this will be simplified form of the given expression.

One number is 6 times a first number .a third is 100 more than the first number .if the sum of the three numbers is 708,find the

Marta_Voda [28]

Say the first number is x, you would then have x and 6x and then x + 100. If you add all these together you get 8x + 100 = 708. You then subtract both sides by 100 and get 8x = 608. Divide both sides by 8 and you get 608/8 which = 76.
