Answer:

Step-by-step explanation:

The triangle shown has all 3 sides equal in length, hence it is an equilateral triangle.

A property of equilateral triangles is the angles are congruent.

The sum of the 3 angles = 180°, hence the measure of each angle is

$\frac{180}{3}$ = 60° → A

Letter A. Which is letter 60 degrees. You can tell since it’s not a right angle, which gets rid of 90 degrees. It’s not 30 degrees because that would be too small. And it’s not 180 degrees because it’s too big.

Solve the equation for<br> x 3/4(x+21) = 10.5 <br> x =

MrRa [10]

<h3>✍️ Answer:</h3><h3> $x=-\frac{294}{13}$ </h3>

✽✽✽✽

$\frac{x\cdot \:3}{4\left(x+21\right)}=10.5$

$\mathrm{Multiply\:both\:sides\:by\:}4\left(x+21\right)$

$\frac{x\cdot \:3}{4\left(x+21\right)}\cdot \:4\left(x+21\right)=10.5\cdot \:4\left(x+21\right)$

$3x=42\left(x+21\right)$

$3x=42x+882$

$\mathrm{Subtract\:}42x\mathrm{\:from\:both\:sides}$

$3x-42x=42x+882-42x$

$-39x=882$

$\mathrm{Divide\:both\:sides\:by\:}-39$

$\frac{-39x}{-39}=\frac{882}{-39}$

$x=-\frac{294}{13}$

How much money would you need to deposit today at 7% annual interest

Monica [59]

Answer:

$33,090.

Step-by-step explanation:

The formula is A = P( 1 + r/2)^2n so we have:

50,000 = P(1 + 0.07/2)^(6*2)

50000 = P * 1.035^12

P = 50000/ 1.035^12

= $33,090 to the nearest dollar.

Pythagorean Theorem a=11 b=60 c=?

zhuklara [117]

Answer:

Step-by-step explanation:

The Pythagorean Theorem is a fundamental in geometry that involves looking at two sides of a right triangle and finding out the length of it. Let's use the formula with the corresponding numbers.

The formula for this question would be $c=\sqrt{a^2 + b^2}$

Since we know that a = 11 and b = 60, we can do the following and substitute :

$c = \sqrt{11^2 + 60^2}$

11 squared is 121

60 squared is 3600

Now we need to add the two number together :

121 + 3600

3721

Since this number is under the square root, we have to square root it. :

$\sqrt{3721}$

Therefore c is equal to 61.
