Answer:
m = 20 and n = 35
Step-by-step explanation:
The triangle on the right has 2 congruent sides and is isosceles
Thus the 2 base angles are congruent, that is
n = 
= 
= 35
The external angle of a triangle is equal to the sum of the 2 opposite internal angles.
110 is an external angle to the triangle on the left, thus
m + 90 = 110 ( subtract 90 from both sides )
m = 20
Answer:
Step-by-step explanation:
interior angle is the angles inside the triangle exterior angle is the angle on a straight line of a triangle

Step-by-step explanation:
For women, the initial number is 6, constant rate of change is w, number of years is x.
<u>Find the rate of change and work out the required formula:</u>
- 10w + 6 = 391 ⇒ 10w = 385 ⇒ w = 38.5
<u>Formula:</u>
<u>Similarly for men, we get:</u>
- 10m + 25 = 410 ⇒ 10m = 385 ⇒ m = 38.5
<u>Formula:</u>

Sorry for the bland explinations havin a bad day.
Step-by-step explanation:
1. The way we solve this is by adding the degrees 72 and 45. then we subtract it by 180. this is because in all triangles the angles always add up to 180 degrees.
2. Like question one what set of angles measures to 180 degrees.
3. The sides of a triangle should define the angle measurements. you can also see if its a triangle if the numbers are continues like 3,4,5 or in this case 4,5,6
4. like in questions 1 and 2 the angles of a triangle has to equal 180 degrees so 60 times 3 is 180 so each angle would have to be 60 degrees.
