Answer: choice A) x = 60, y = 30
==================================================
Focus on the smaller triangle on the left side. This is an equilateral triangle with all angles the same measure. So we have three angles each x degrees. They add to x+x+x = 3x. Set this equal to 180 (all angles of any triangle add to 180) and solve
3x = 180
x = 180/3
x = 60
Since all three angles of that triangle are each 60 degrees, this means that the base angle of the smaller triangle on the left is y = 90 - x = 90 - 60 = 30.
Put another way, x+y = 60+30 = 90 because the angles x and y form the 90 degree right angle. See the attached image for more info.
note: the triangle on the right side is an isosceles triangle. The base angles are congruent, and these angles are opposite the congruent sides (marked with the tickmarks).
Answer:
i'd guess 1/3, because that cup looks 1 third smaller than the toe.

Answer:
-9/8
Step-by-step explanation:
The two points given are
(1,6) and (9,-3)
The slope is given by
m = (y2-y1)/(x2-x1)
= (-3-6)/(9-1)
= -9/8
Answer:
54.67 cm²
Step-by-step explanation:
Given that the two sides of Δ ABC are 8.2 cm and 13.5 cm and the angle included by those sides is 81°.
Let, b = 8.2 cm and c = 13.5 cm and ∠ A = 81°
Hence, area of triangle ABC, Δ =
⇒ Δ =
⇒ Δ =
⇒ Δ = 54.67 cm² (Answer)
