You need to find the surface area of the rectangular prism and the triangular prism and add them up to find the answer.
Rectangular prism:
SA=2(lw+wh+lh)
SA=2(437.5+406.25+1137.5)
SA=2(1981.25)
SA=3962.5 sq cm
Triangular prism:
SA=2(1/2bh)+3(slanted height)*w
SA=2(235.75)+3(293.75)
SA=471.5+881.75
SA=1352.75 sq cm
3962.5+1352.75=5315.25 sq cm
4+3x
2x-5
2(8+x)
2x-5=4+3x
-x-5=4
-x=9
x=-9
Answer: Choice B
95 - 1080n for any integer n
=================================================
Explanation:
Notice how 1080 is a multiple of 360 since 360*3 = 1080. The other values 1450, 780 and 340 are not multiples of 360. For example 1450/360 = 4.02777 approximately. We need a whole number result to show it is a multiple.
Therefore, choice B shows subtracting off a multiple of 360 from the original angle 95. In my opinion, it would be better to write 95+360n or 95-360n to make it more clear we are adding or subtracting multiples of 360.
Choice B will find coterminal angles, but there will be missing gaps. One missing coterminal angle is 95-360 = -265 degrees. So again, 95-360n is a more complete picture. I can see what your teacher is going for though.
Answer:
<em>180/7 deg and 1080/7 deg</em>
Step-by-step explanation:
The measures of two supplementary angles add to 180 degrees.
One angle measures x.
The supplement measures 6x.
The sum of the measures is 180 deg.
x + 6x = 180
7x = 180
x = 180/7
6x = 1080/7
