Answer:

The length of the unknown side is 10 meters

Step-by-step explanation:

we know that

In this problem we have an isosceles right triangle

Applying the Pythagorean Theorem

$c^2=a^2+b^2$

where

c is the hypotenuse (unknown side)

a and b are the legs

we have

$a=7\ m\\b=7\ m$

substitute

$c^2=7^2+7^2$

$c^2=(2)7^2$

$c=7\sqrt{2}\ m$

$c=9.9\ m$

Round to the nearest whole number

$c=10\ m$

therefore

The length of the unknown side is 10 meters

Answer:

(2 · 10⁰) + (5 · 109)

= (2 · 0) + (5 · 109)

= 2 + (5 · 109)

= 2 + 545

= 547

In a triangle, the measure of the first angle is three timesthree times the measure of the second angle. the measure of the thi

polet [3.4K]

1st angle = 3x

2nd angle = x

3rd angle = 65 +x

3x + x +65+x = 180

5x+65 = 180

5x=115

x = 115/5 = 23

2nd angle = 23 degrees

1st angle = 23 x 3 = 69 degrees

3rd angle = 65 +23 = 88 degrees

need help finding the definition of power of a product property, power to a power property, and power of a quotient property.

postnew [5]

The Power of a Product property tells us that when you multiply two numbers with the same base, you can add their exponents to determine the product.
For example, $x^{a}$ * $x^{b}$ = $x^{a+b}$ .

The Power of a Quotient Property tells us that when you divide two numbers with the same base, you can subtract their exponents to determine the quotient.
For example, $x^{a}$ / $x^{b}$ = $x^{a-b}$

neonofarm [45]

Answer: My teacher posted a review, and this question was on it. In the answer key, it said that:

A= 2

B= 1335

C= 0

This confused me a lot and I'm not quite sure how she got that answer.
