Answer: 45°
Step-by-step explanation:
Given that :
∠A=5x−15°---(1)
∠B=2x+21°----(2)
Equating
∠A = ∠B
(5x−15)° = (2x+21)°
5x - 15 = 2x + 21
Collecting like terms
5x - 2x = 21 + 15
3x = 36
x = 12
Substitute x = 12 in either angle A or B since both are congruent
∠A=(5x−15)°
∠A = (5(12) - 15)°
∠A = (60 - 15)°
∠A = 45°
∠A = ∠B = 45°

Hi ! I need help with some questions please help me
Answer:
x = 6
HI = 29
Step-by-step explanation:
✔️HI = ½(AB) => Triangle Mid-segment Theorem
HI = 5x - 1
AB = 58
Plug in the values and solve for x
5x - 1 = ½(58)
5x - 1 = 29
Add 1 to both sides
5x - 1 + 1 = 29 + 1
5x = 30
Divide both sides by 5
5x/5 = 30/5
x = 6
✔️HI = 5x - 1
Plug in the value of x
HI = 5(6) - 1
HI = 30 - 1
HI = 29
Answer:
Using the visual, 20 blocks, but you still need to change it to match the problem's scale
Step-by-step explanation:
First just try to find a way out and count the blocks. That's what I did. The part I haven't done is scale it. As the starting and end points of the grid are given, but where they fall is not clear, I don't know what the block to number ratio is. Sorry, maybe ask a teacher, they shouldn't take off any points.
