23
Step-by-step explanation:
idk how i got that but i guess search it up
take 888.99, multiple it by 1.0775 (tax plus original price) to get the answer (957.886725 or 957.889)
Both of the other angles are 40° because a triangle has a total angle of 180° and an isosceles triangle means that at least two of the sides have to be the same length (two angles must be the same)
180 - 100= 80
80 ÷ 2 = 40
Answer:
Since all the three sides of the triangle are of equal length, we can find the perimeter by multiplying the length of each side by 3. 20 + 20 + 20 = 3 × 20 = 60 cm.
