Please help me prove that ED is congruent to BA! I thought I had it right by proving right and vertical angles, but I’m missing

Vikki [24]

Step-by-step explanation:

$\overline{DA} \text{ bisects } \overline{EB}$ is given

$\overline{BC} \cong \overline{EC}$ definition of <u>bisect</u>

<u /> $\overline{EB} \perp \overline{ED}, \, \overline{EB} \perp \overline{BA}$ are both given

<u /> $\angle B, \, \angle E \text{ are right angles}$ definition of perpendicular

$\angle B \cong \angle E$ because all right angles are congruent

$\angle{ACB} \cong \angle{DCE}$ vertical angles are congruent

$\triangle{ACB} \cong \triangle{DCE}$ ASA (angle-side-angle)

$\overline{ED} \cong \overline{BA}$ CPCTC (corresponding parts of congruent triangles are congruent)

In ΔOPQ, the measure of ∠Q=90°, PQ = 3.6 feet, and OP = 9.1 feet. Find the measure of ∠P to the nearest tenth of a degree.

svetlana [45]

Step-by-step explanation:

$\because \cos \: \angle P = \frac{PQ}{OP} \\ \\ \therefore \: \cos \: \angle P = \frac{3.6}{9.1} \\ \\ \therefore \: \cos \: \angle P = 0.3956 \\ \\ \therefore \: \cos \: \angle P = \cos \: 66.6966 \\ \\ \huge \red{ \boxed{\therefore \: \angle P = 66.7 \degree}}$

I really need help on this question, because I forgot of how to find the angle of each variable.

juin [17]

Answer:

a = 38 degree

b = 54 degree

c = 54 degree

Step-by-step explanation:

a = 180 - 142 = 38 ( angle on a straight line is equal to 180)

To determine the value of b, we have to find the other missing angle in the triangle.

the value of the missing angle is 38

Alternate angles are equal. the missing angle is alternate to angle b which has a value of 38

b = 180 - (38 + 88) = 54

c = 54
