B, there's only two kinds of acute triangles ands that's a 45,45,90 and a 30,60,90.
Answer:
<u>The two numbers are 23 and 56</u>
Step-by-step explanation:
Let's say the two numbers are A and B.
We are told:
1) A+B=79
2) 3A+5B=283
Let's take the first expression and solve for A:
A+B=79
A=79-B
Now use this value of A in the second expression:
3A+5B=283
3(79-B)+5B=283
237-3B+5B=283
2B = 46
B = 23
Since B=23, we know from 1) that
A+B=79
A+23=79
A = 56
<u>CHECK:</u>
Does A+B=79?
56+23 = 79? <u>YES</u>
Does 3A+5B=283?
3(56)+5(23)=283
168 + 115 = 283? <u>YES</u>
The answer is 35 bc it has pointed on the dot
810/10.8 = 75 ...so as the answer
Answer:
AB = 3.3 cm
Step-by-step explanation:
The formula to find out area of a regular octagon is given by

where a is the length of each side of the regular octagon.
Plugin A=54 into the formula

Divide both sides by 2


Plugin √2 as 1.41


Divide both sides by 2.41


Taking square root on both sides

a = 3.346
a = 3.3 cm (rounded to nearest tenth)
so, length of side AB = 3.3 cm
