A triangle has three angles, and their measures add up to 180 degrees.
An isosceles triangle has at least 2 congruent sides, and the angles opposite the congruent sides are congruent.
This triangle has one angle of 40 deg, and two angles that measure the same; call the measure of each base angle x.
x + x + 40 = 180
2x + 40 = 180
2x = 140
x = 70
The base angles measure 70 deg.

Answer:
9/25 units^2
Step-by-step explanation:
AREA(Square) = side * side = 3/5 *3/5 = 9/25 square units
Answer: 9/25 units ^2 :)
The sum of the sides of a quadrilateral is equal to 360º.
x= 4th angle measurement
We have the following equation:
90+156+28+x=360
x=360-90-156-28
x=86
Answer: the size of the 4th angle would be 86º.
Answer:
Circumference=16pi
Arc Length=8pi
Step-by-step explanation:
Circumference formula=2(pi)(r), or d(pi)
The arc is only half of that in this case, therefore you would only pi(r) or 1/2(d)(pi).
