Answer:
Dividing each part into 10 and then summing the results up, is equivalent to dividing 89.5 into 10.
Step-by-step explanation:
This example refers to the Distributive Property of the division, which is valid when the dividend is decomposed.
A simple example could be: 400 ÷ 10 = (200 ÷ 10) + (200 ÷ 10)
In the exposed example we know that 89.5 = 80 + 9 + 0.5.
(80/10) + (9/10) + (0.5/10) =
8 + 0.9 + 0.05=
8.95
89.5/10 = 8.95

Answer:
45
Step-by-step explanation:
<u>First we want to understand the Base Angles Theorem</u>
The Base Angles Theorem tells us that the base angles or the two bottom angles of an isosceles triangle are congruent.
Using this theorem, we can say that angle A and angle G are congruent meaning m∠A = m∠G. We can then write both of them as x.
We can create the equation ∠N + ∠A + ∠G = 180 degrees.
Knowing ∠N and knowing ∠A + ∠G = 2x, we can rewrite the equation into
<em>90 + 2x = 180</em>
We can then solve for x,
<em>90 + 2x - 90 = 180 - 90</em>
<em>2x = 90</em>
<em>2x / 2 = 90 / 2</em>
<em>x = 45 </em>degrees
