-2/3x + 2.8 = -8.2 what is x
Add 2.8 on both side of the equation
-2/3x=-11
Divide both side by -2/3
x=33/2
Check: -2/3(33/2)+ 2.8 = -8.2
-11+2.8=-8.2
-8.2=-8.2
Answer is x=33/2
Answer:
B
Step-by-step explanation:
Answer:
b = 128.3 inches
Step-by-step explanation:
We know Angle A is 41° and the HYPOTENUSE (the longest side) is 170. We're looking for side b, which is the ADJACENT side (adjacent means next to, like it's literally a part of the angle A) The trig function that puts together ADJ and HYP is the cosine function.
cos 41 = ADJ/HYP
cos 41° = b/170
170cos 41° = b
You need a calculator to get a value for cos 41°. You could put in the entire 170cos41° into a calculator all at once.
128.3 = b
b = 128.3 inches
