Answer:

-15

Step-by-step explanation:

Given:

x=-7
-14+7=x+8

Simply plug in and see if the statement is true. If not, isolate x.

Test for truth:

-14+7=-7+8
-7=1
NOT true.

Isolate x in original equation:

-14+7=x+8
-14+7-8=x
-7-8=x
-15=x

What is the value of the expression? Enter the answer in the box.<br> 4+(8 - 7) X6-1

e-lub [12.9K]

Answer: 9

Explanation: you would use PEMDAS to solve the algebraic expression first by doing parentheses so subtract 8 and 7 which leaves you with 4 + 1 times 6-1. You would then multiply 1 into 6 which would leave you with 4 + 6 - 1 which you would then sum up 4 and 6 which leaves you with 10-1 which would give you the answer of 9

So the answer would be 9

Hope this helps!

A, b and c are the sides of a right triangle, where side a is across from angle a, side b is across from angle b, and side c is

Vera_Pavlovna [14]

<span>Find missing length :
</span>
a² + b² = c²
c² = 19² + 34²
c² = 1517
c = √1517
c = 38.95 units.

Find missing angle A:

$\dfrac{a}{\sin(a)} = \dfrac{c}{\sin(c)}$

$\dfrac{19}{\sin(a)} = \dfrac{38.95}{\sin(90)}$

$\sin(a) = 0.488$

$a = sin^{-1} (0.488)$

$a = 29.2 \textdegree$

Find Missing B:

$\dfrac{b}{\sin(b)} = \dfrac{c}{\sin(c)}$

$\dfrac{34}{\sin(b)} = \dfrac{38.95}{\sin(90)}$

$\sin(b) = 0.873$

$b = sin^{-1}(0.873)$

$b = 60.8 \textdegree$

Answer: Missing length = 38.95 units ; Missing angles = 29.2° and 60.8°
