Please help me find the value of x the answer must be exact

jenyasd209 [6]

Answer:

$x=11$

Step-by-step explanation:

This is a 45°-45°-90° triangle. The two legs are the same length, and the hypotenuse is that length times the square root of two:

$leg=x\\hypotenuse=x\sqrt{2}$

Therefore, the value of x is 11.

You can double-check using the sine ratio:

$sineX=\frac{opposite}{hypotenuse}$

Insert the values:

$sin45=\frac{x}{11\sqrt{2} }$

Insert the equation into a calculator:

$x=11$

:Done

*It's important to know that, when working with trigonometry ratios, the hypotenuse is never considered the adjacent or opposite side, and the 90° angle is never used in the ratios.

Please help me simplify these expressions: 1) -12+3(7-4)+5 2) 3(15-2•6)-5

erastova [34]

Remember Pedmas. 1) -12+3(3)+5 = -12+9+5 = 2. 2) 3(15-12)-5 = 3(3)-5 = 4

Sharon earns $25 per item she sales plus a base salary of $100 per week. Write and solve an inequality to find how many items sh

artcher [175]

$25 per item sold + $100 per week = 700 total goal in 1 week

X is our items sold variable. We only use 100 since our goal is for only one week.
25x + 100 = 700

Subtract 100 from each side.
25x = 600

Divide by 25.
x = 24
