Answer:
CB = 5, 
Step-by-step explanation:
Assuming that the marks next to angle D mean that
, then there is enough information to conclude that the two right triangles are congruent (HA theorem--hypotenuse/angle).
Then all the corresponding parts of the two triangles are congruent, including segments BA and BC, making them the same length.
4x + 1 = 9x - 4
Solving for x,
1 = 5x - 4
5 = 5x
1 = x
Pluggint x = 1 into the two expressions reveals that the length of segment CB is 5.
The two small angles at D are congruent, so
.
Complementary angles sum to 90°
the complement of 64° = 90° - 64° = 26°
Answer: We need to know the value of y >:3 Tricky Tricky
Step-by-step explanation:
A = P + PRT....for T
A - P = PRT
(A - P) / (PR) = T
