Answer:
Step-by-step explanation:
In an isosceles triangle, by definition two of the three sides of the triangle are equal to one another. Therefore, the angles opposite to these sides must also be equal. And considering the Triangle Sum Theorem, the angles of a triangle must add up to 180 degrees, the angle that measures 124 degrees cannot be be equal to another angle due to the fact that the sum of them would exceed 180. Therefore let x be the angle:
124+2x=180
2x=56x=28
Please brainlest!
we know that
tenths is equal to
% is equal to
so
tenths greater than% is equal to add
therefore
the answer is
ab^2 = be^2 + ae^2 pythagorean theorem e is the point below b
6.5^2 = 6^2 + ae^2
42.25 = 36 +ae^2
6.25 = ae^2
2.5 = ae
23 = ae +ef +fd f is the point below c
23 = 2.5 + 9 +fd
fd = 11.5
tan D = opp/adj
tan D= cf /fd
tan D = 6/11.5
D = tan^-1 (6/11.5)
D =27.5528
D = 27.6 degrees
The correct answer is a
(X+1)^2 - x^2=23
X^2 + 2x + 1 -x^2 =23
2x +1 =23
2x =22
X= 11
X+1= 12
