Answer:

DE = 80.

Step-by-step explanation:

Since the 2 lines are congruent:

5x = 3x + 32

2x = 32

x = 16

So DE = 3(16) + 32

= 48 + 32

= 80.

Given that A, O & B lie on a straight line segment, evaluate obtuse ∠AOC.
Evgesh-ka [11]

Answer:

AOC = 124°

Step-by-step explanation:

Angle on a straight line is 180°, therefore, the sum of the three angles shown is 180;

This can be written like so:

(3x + 94) + (x + 30) + (2x - 4) = 180

This equation can be solved to find x:

6x + 120 = 180

6x = 180 - 120

6x = 60

x = 10

AOC = 3(10) + 94

= 30 + 94

= 124
