Answer:
Step-by-step explanation:
Since the two triangles are congruent, all their angles are as well.
So you can set 4y-10 = 3y+5 since they are the same angles.
Now solve the system by putting the y's on the left side and coefficients on the right side:
y=15.
The area of his the room is20.34375, or 20 11/32. I hope this helps.
Let’s start with the easy part: half of the base is 3.
Therefore, 3 x h + 1 = 18
3 x h = 3h and 3 x 1 = 3
3h + 3 = 18
To solve these equations, you have to do the inverse. First you would need to minus 3:
3h = 15
3h is a simpler way of saying 3 x h, so the inverse would be a divide.
h = 5
Answer:
Step-by-step explanation:
<h3>Parallel lines and transversal:</h3>
Linear pair: When the uncommon arms of two adjacent angles form a straight line, the adjacent angles are called linear pair and they add upto 180
3) ∠3 + ∠2 = 180
65 + ∠2 = 180
∠2 = 180 - 65
<h3> ∠2 = 115°</h3>
When parallel lines are intersected by transversal, alternate exterior angles are congruent.
a // b and d is transversal.
∠5 = ∠11
∠5 = 100°
When parallel lines are intersected by transversal, the alternate interior angles are congruent.
a // b and c is transversal
m∠13 = ∠3
∠13 = 65°
4) ∠3 & ∠14 are co-interior angles. Co-interior angles are supplementary.
∠3 + ∠14 = 180
65 + ∠14 = 180
∠14 = 180 - 65
∠14 = 115°
∠5 + ∠8 = 180 {Linear pair}
100 + ∠8 = 180
∠8 = 180 - 100
∠8= 80
∠9 = ∠11 {vertically opposite angles are congruent}
∠9 = 100
∠ 3 + ∠14 + ∠ 8 + ∠9 = 65 + 115 + 80 + 100
= 360°
