Answer:
m∠8 = 49°
Step-by-step explanation:
∠7 and ∠8 are same-side interior angles.
Remember, same-side interior angles are supplementary. This means that the sum of the angles is 180°.
Let's use the variable 'x' to represent the unknown measure of angle ∠8.
(cancels itself out)
Therefore, the measure of ∠8 is 49°.
Answer:
the area of the trapezoid is 32
Step-by-step explanation:
a (base)2
b (Base)6
h (height)8
3,500 is the best estimate if you multiply 7 by round 456 to 500 so 7x500=3,500
Answer: Only one.
Step-by-step explanation:
We are given that in a triangle two side lengths of 10 centimeters and 8 centimeters. The angle between the sides measures 40°.
Suppose there is also a triangle with the same measures.
Then both the triangles are congruent by SAS congruence postulate.
Thus, every triangle with the given measurement are congruent to each other by SAS postulate.
Therefore, only one triangle can be possible with the given measurement.
Answer:
18 weeks
Step-by-step explanation:
80+15x=350
15x=270
x=270/15
x=18
