Answer:

x=31

Step-by-step explanation:

you just have to add the two equations to equal 180 because it's they're supplementary angles.

(25+x)+4x=180

25+x+4x=180

25+5x=180

5x=155

x=31

A circle is centered on point b . Points a,c, and d lie on its circumference . If adc measure 61 then what does abc measure.

Elis [28]

Answer:

$\angle ABC = 122^\circ$

Step-by-step explanation:

Given

$\angle ADC = 61^\circ$

<em>See attachment for circle</em>

Required

Find $\angle ABC$

From the attachment, we can see that:

$\angle ADC$ is at the circumference

$\angle ABC\\$ is in at the center

From cyclic theorems,

The relationship between ABC and ADC is:

$\angle ADC = \frac{1}{2} * \angle ABC$

Make ABC the subject

$\angle ABC = 2 * \angle ADC$

Substitute: $\angle ADC = 61^\circ$

$\angle ABC = 2 * 61^\circ$

$\angle ABC = 122^\circ$
