In order to answer the question, you need to know the formula area of an ellipse.
Area = pi * a * b
a = minor axis
b = major semi-axis
Area = 3.14 * 20 * 14
Area = 879.20 cm^2
Step-by-step explanation:
the sum of all angles in a triangle is ALWAYS 180°.
and by using the word "congruent" : for angles that only means they are equally large.
we know the third angle.
so,
180 = P + Q + R = 2×P + 28.45
(because P = Q)
2×P = 151.55
P = Q = 151.55 / 2 = 75.775°
Answer:
x = 120°
Step-by-step explanation:
the 165 degree obtuse angle forms a straight line with the upper left angle inside the triangle, therefore this angle measures 15 degrees
we know two of the three angle measures so we add all three together to find the unknown angle
x + 15 + 45 = 180
x + 60 = 180
x = 120°
Answer:
4 i believe
Step-by-step explanation:
Im so sorry if this is wrong and for being late
The material costs 5.37 for 1 yard.
Multiply the cost of 1 yard by the number of yards bought:
5.37 per yard x 4.75 yards = $25.51 Total cost.
The answer would be D.
