Answer:
(8,6)
Step-by-step explanation:
Solve by elimination!
-2x-y=-22
2x-6y=-20
cross out, and merge!
-7y=-42
y = 6
Plugin y in one equation (I choose the easy one XD)
-2x-6=-22
-2x=-16
x = 8
Answer is 138
Just do 180-42 to get angle A
And then you can also find angles B and C, since B is vertical angles with 42, then that means it’s also 42, and C is the same way with angle A.
Answer:
Step-by-step explanation:
According to the trapezoid area formula, the area of a trapezoid is equal to half the product of the height and the sum of the two bases. Area = ½ x (Sum of parallel sides) x (perpendicular distance between the parallel sides). Where, h is the height and b1 and b2 are the parallel sides of the trapezoid.
-12 and -20 degrees since they are lower numbers and colder bc it goes down the temp.
