Answer:
x = 10°
Step-by-step explanation:
The diagonals of a rhombus divide the figure into congruent right triangles. That means the two marked acute angles are complementary.
__
<h3>solve for x</h3>
Complementary angles total 90°, so the relation we can use to find x is ...
(3x -13) +(8x -7) = 90
11x = 110 . . . . . . . . . add 20
x = 10 . . . . . . . . . divide by the coefficient of x
The value of x is 10°.
(a + 2b) • (a2 - 2ab - 4b2)
Answer:
C) Similar-SAS
Step-by-step explanation:
Here,
BSE ~ TES
Now,
BS = TE (:• being corresponding side )
BSE = TES (:• Being Corresponding angle
SE = SE (:•Being corresponding side)
Therefore,
the given triangle is similar by
SAS axiom
