Answer:
38 square inches
Step-by-step explanation:
The figure is a quadrilateral with one pair of parallel sides. That means it is a trapezoid, so the area formula for a trapezoid is applicable.
A = (1/2)(b1 +b2)h
The two parallel bases are 7 in and 12 in. The height is the perpendicular distance between them, 4 in. So, the area is ...
A = (1/2)(7 in +12 in)(4 in) = (1/2)(19 in)(4 in)
A = 38 in²
The area of the trapezoid is 38 square inches.
Answer:
x=11
Step-by-step explanation:
Due to angles DCA and CAB being Alternate Interior Angles, we know that they will be equal. This means that
°
Next, we can find the measure of the angle DCE.
Angles BCE and BCA are supplementary. This means that they will add together to be 180°
This means that 180-BCE=BCA
Which means 
As all of the angles in a triangle must add together to be 180 degrees, we can set up the following equation
Answer:
60 degrees
Step-by-step explanation:
It is less than 90 degrees
Answer:
B
Step-by-step explanation:
Supplementary angles sum to 180°
If one angle is 77°, then the other angle is
180° - 77° = 103° → B
