Step-by-step explanation:
Cos(-x) = cos(x)
Therefore, cos(-x)= -0.65
Let
x = measure of angle TAP
y = measure of angle BRE
We're told that "angle BRE is its own complement" meaning that angle BRE added to itself is 90 degrees. In algebraic terms, we can say
y+y = 90
2y = 90
2y/2 = 90/2
y = 45
So angle BRE is 45 degrees. Note how 45+45 = 90.
We also know that angle TAP and angle BRE are supplementary. They add up to 180 degrees
x+y = 180
x+45 = 180 ... replace y with 45
x+45-45 = 180-45 ... subtract 45 from both sides
x = 135
Since we defined x to be the measure of angle TAP, this means that angle TAP is 135 degrees
I would say C because you multiply 3 x H then 3 x4 I think this is the right answer but I'm not so sure though Hope it helped sort of - Ashlynn
A
Step-by-step explanation:the answer is you have 8 quarter and 13 dimes .
Because you have 5 more dimes than quarters which will equal 3 dollars and 30 cents
For multiple-choice questions, it is often faster to check the answers than to try to figure out what the answer should be.
Only selections (A) and (D) match the first entry in the table.
Of those, only selection (A) matches the second entry in the table.
The appropriate choice is ...
(A) y = x + 9
