Hello,
7x-4y=-8 (1)
y=3/4x-3==>3x-4y=12 (2)
(1)-(2)==>4x=-20 ==>x=-5
if x=-5 then (1)==>4y=-35+8==>y=-6.75
Answer B
The sum of all exterior angles add up to 360º. To find the missing 3rd exterior angle subtract the sum of the first two exterior angles from the total sum of all exterior angles.
360º - 220º = 140º
The measure of the third exterior angle is 140º.
Answer:
300 in³
Step-by-step explanation:
Hello There!
The prism shown is a rectangular prism
The formula for volume of a rectangular prism is
where l = length w = width h = height
so we are given all of the dimensions so to find the volume all we have to do is plug in the values into the formula
so
Too easy
remember all angles in traingle add to 180
straight lnes are 180
so
35+59+x=triangle
35+59+x=180
x=86
x+y=line
x+z=180
86+z=180
z=94
11+z+y=triangle
11+94+y=180
y=75
x=86
y=75
z=94
