Answer:
a) 39 degrees
Step-by-step explanation:
angle REB + angle JEB = 180 degrees (because J, E, and R are collinear)
=> angle REB = 180 - angle JEB = 180 - 132 = 48 degrees
angle REB + angle ERB + angle RBE = 180 degrees (because the sum of 3 angles inside a triangle is 180 degrees)
=> angle RBE = 180 - angle REB - angle ERB = 180 - 48 - 93 = 39 degrees
Okay so, the formula we can use for this problem will be x= 410/.82, x being the original price of the TV. The .82 was figured to make up for the 18% lost from the original price. 410/.82=500. so the original price of the TV would be $500. To check our answer we can multiply 500 by the sale price and subtract that amount from the original $500. Like so: 500-(500*.18)=410.
Answer:
40,000
Step-by-step explanation:
Answer:
28000
Step-by-step explanation:
Area is l times w times h
50 times 20 is 1000.1000 times 28 is 28 thousand
So 140=origonal price-1/5 so
represent origonal price with p
140=4/5p
multiply both sides by 5/4
175=p
the answer is 175
