Angle 3 = angle 7 [alternate angles]
=> 4x+1 = 2x + 21
=> 4x-2x = 21-1
=> 2x = 20
=> x = 20/2
=> x = 10

When comparing the ratio 9^2 to 9^7 luciano calculated 1/9^5 is luciano correct and why or why not

Leto [7]

Answer:

yes

Step-by-step explanation:

using the rule of exponents

$\frac{a^{m} }{a^{n} }$ = $\frac{1}{a^{(n-m)} }$ , then

$\frac{9^2}{9^{7} }$ = $\frac{1}{9^{(7-2)} }$ = $\frac{1}{9^{5} }$

In △ABC, m∠A=50∘, m∠B=60∘, and m∠C=70∘.

kiruha [24]

Given:

In $\Delta ABC, m\angle A=50^\circ, m\angle B=60^\circ$ and $m\angle C=70^\circ$ .

$\Delta ABC$ is rotated $90^\circ$ counterclockwise to $\Delta XYZ$ .

To find:

The measure of angle Z.

Solution:

We know that the rotation is a rigid transformation. It means the image and figure are congruent to each other.

$\Delta ABC$ is rotated $90^\circ$ counterclockwise to $\Delta XYZ$ . So, $\Delta ABC\cong \Delta XYZ$ .

$\angle C\cong \angle Z$ (CPCTC)

$m\angle C=m\angle Z$

$70^\circ=m\angle Z$

Therefore, the measure of angle Z is 70 degrees.
