Write an equation that relates the angle in a triangle. The measure of angle A is 45 degrees. The measure of angle B is b degree

Korolek [52]

Since the interior angles of a triangle equal 180°, then 180-45=135.

Then you would use 135 to find the remaining two angles: b+3b=135.
4b=135.

Divide to find b. And the plug in whatever b is for the to figure out Angles B and C.

However, I believe the equation it's looking for is: 180=45+b+3b OR 45+4b=180

Za and Z6<br> are<br> complementary angles. Za measures 78°.<br> What is the measure of Zb?

VARVARA [1.3K]

Answer:

$\boxed{\angle b = 12 \degree}$

Given:

$\angle a \: and \: \angle b \: are \: complementary \: angles\\ \\ \angle a = 78 \degree$

Step-by-step explanation:

Two Angles are Complementary when they add up to 90° (a Right Angle).

$= > \angle a + \angle b = 90 \degree \\ \\ = > 78 \degree + \angle b = 90\degree \\ \\ = > \angle b = 90 \degree - 78 \degree \\ \\ = > \angle b = 12 \degree$
