Refer to the map shown in Exercise 2. If m∠1 is 64˚, what is the measure of ∠2?
zmey [24]
<h2>Explanation:</h2><h2></h2>

Hello! Remember you have to write complete questions in order to get good and exact answers. Here you haven't provided any figure, so I'll assume m∠1 and m∠2 are complementary angles. Angles that add up to 90° are called complementary angles. In this case, we know m∠1 and want to know m∠2. Thus, we can establish the following formula:

m∠1 + m∠2 = 90°

Isolating m∠2:

m∠2 = 90° -  m∠1

m∠2 = 90° -  64

m∠2 = 26°

Which expression is equivalent to StartRoot StartFraction 25 x Superscript 9 Baseline y Superscript 3 Baseline Over 64 x Supersc
MAVERICK [17]

Answer:

\displaystyle \frac{5x}{8y^{4}}\sqrt{x}

Step-by-step explanation:

<u>Simplfy in Algebra </u>

We have the following expression

\displaystyle E=\sqrt{\frac{25x^9y^3}{64x^6y^{11}}}

Simplifying like factors in the denominator and numerator

\displaystyle E=\sqrt{\frac{25x^3}{64y^{8}}}

All the factors are perfect squares except x^3, thus we rewrite:

\displaystyle E=\sqrt{\frac{25xx^2}{64y^{8}}}

Taking the square root of all the perfect square factors:

\boxed{\displaystyle E=\frac{5x}{8y^{4}}\sqrt{x}}

Answer:

1. The angles of a triangle added up all together is 180. So, we can solve a as an equation!

36+57+a=180.

From this, we can figure out a:

a=87

2. The same goes for this one, just a bit different. We write our equation like this:

3x+90=180

we solve this:

3x=90

we divide both sides by 3 and get:

x=30
