Answer:

missing angle = 67.8 degrees

Step-by-step explanation:

$cos-1 = \frac{adjacent}{hypotenuse}$

$cos-1 = \frac{5.3}{14}$

$cos-1 = 0.378571428$

$67.754 = 67.8$

What is Y increased by 22

Shalnov [3]

Answer:

y+22

Step-by-step explanation:

Increased by just means addition. so y increased by 22 would translate to y+22.

Hope I helped :)

What are the solutions to the quadratic equation below x^2+20x+100=7

aleksandrvk [35]

First you must have the quadratic equal to zero. In order to do this you must subtract 7 to both sides

x^2 + 20x + (100 - 7) = 7 - 7

x^2 + 20x + 93 = 0

Now you must find two numbers who's sum equals 20 and their multiplication equal 93

Are there any? NO!

This means that you have to use the formula:

$\frac{-b±\sqrt{b^{2} - 4ac} }{2a}$

In this case:

a = 1

b = 20

c = 93

$\frac{-(20) plus/minus\sqrt{20^{2} - 4(1)(93)} }{2*1}$

$\frac{-20 plus/minus\sqrt{400 - 372} }{2}$

$\frac{-20 plus/minus\sqrt{28} }{2}$

^^^We must simplify √28

√28 = 2√7

so...

$\frac{-20 plus/minus 2\sqrt{7} }{2}$

simplify further:

$-10 plus/minus\sqrt{7$

-10 + √7

-10 - √7

***plus/minus = ±
