Explanation:

b and 50 are supplementary angles (they add up to 180), so create an equation by adding them up to equal 180:

b + 50 = 180

we want the x by itself, so subtract both sides by 50 to get:

b = 130°

PLEASE HELP ME :) I DID THIS PROBLEM 7 TIMES AND ITS STILL WRONG PLEASE
fiasKO [112]

Answer: $95450

Step-by-step explanation:

We obviously want to look in the 3rd column.

Income that can be taxed is within interval for 33%, so (0.33)(315000) = $103950.

Subtract the tax credit, and we get $103950 - $8500 = $95450.

A square pyramid is shown. What is the surface area?
ICE Princess25 [194]

Answer:The answer is B


Step-by-step explanation:

first find te height:

1.5/2=0.75 (this will be your "b" of the pythagorean theorem for finding the height)

now do the  pythagorean theorem:

a^2+0.75^2=3^2

(height)= 2.905

A= a^2+2a√((a^2/4)+h^2)

a (base edge)= 1.5

h (height)= 2.905

Calculate and you get B as your answer.


Hope this elpsand you get this right!
