Answer:
<h2><u>111°</u></h2>
Step-by-step explanation:
Hi,
So lets answer this question;
Here we know that:
69° + z = 180° [Straight angle or Supplementary angle]
⇒ z = 180° - 69°
= <u>111°</u>
Z/1 = 32/1
8 = 8/1
8/1 : 1/4 = 8/1 • 4/1 = 32
Answer:

All triangles have 3 sides that are equal in length.f(3,4,5)
Only some triangles have 1 right angle.t
All triangles are polygons.t
All triangles have 3 angles.t
<u>Answer:</u>
∠DBC = 40°
<u>Step-by-step explanation:</u>
We are given a figure where we know that the angle m∠1 = 65°, m∠2 = 60° and m∠6 = 85°. With the help of these given measures of the angles, we are to find the measure of the angle m∠DBC.
Since the sum of angles in a triangle is equal to 180 degrees, so:
∠1 + ∠2 + ∠3 = 180
∠3 = 180 - (65 + 60)
∠3 = 55°
Also ∠6 and ∠B are alternate interior angles so if ∠6 = 85° then ∠B is also = 85°.
Now that we know ∠3 and ∠B, we can find ∠DBC:
∠DBC = 180 - (85 + 55)
∠DBC = 40°
Divide them and then multiply
