Answer:
62°
Step-by-step explanation:
Since the triangle is isosceles then the 2 base angles are congruent.
Given there is one angle measuring 56° then it must be the vertex angle.
Thus the 2 congruent base angles are
[tex]\frac{180-56}{2}[/tex] = [tex]\frac{124}{2}[/tex] = 62°

Is the triangle with leg lengths of 8 mm and 8 mm and a hypotenuse of length 12 mm a right triangle?
Answer:
No
Step-by-step explanation:
Use the Pythagorean Theorem to check on this.
Does 8^2 + 8^2 = 12^2? Does 64 + 64 = 144? NO. So this is not a right triangle.
If you know the area and the base of a triangle, how can you find the height?
Answer: do your values into the equation A=1/2bh and do the math. First multiply the base (b) by 1/2, then divide the area (A) by the product. The resulting value will be the height of your triangle!
pls help im pretty sure its easy i just forgot
the average can be calculated by adding the scores together and then dividing by the number of scores.
we can set up an equation:
let x = test score needed on next test
(72+72+80+x)/4 = 71
multiply both sides by 4
72+72+80+x = 284
add like terms
224+x=284
subtract 224 from both sides
x=60
she will need a 60 for her average to be 71
She needs to score a 60 to have a average score of 71,
72+72+80+60=284
284/4=71

Ruth read a total of 14 books over 7 months. After belonging to the book
club for 10 months, how many books will Ruth have read in all? Assume
the relationship is directly proportional.
Answer:
20 books
Step-by-step explanation:
Well 14 books in 7 months.
Find the unit rate
14/7=2
So 2 books each month
We have Ruth here that was in the book club for 10 months.
And since 2 books each month,
2*10=20
20 books

Convert: 76 ounces = _____ pounds _____ ounces
Answer:
4 pounds 12 ounces
Step-by-step explanation:
there are 16 ounces in 1 pound so 76/16 = 4.75 and .75 is equal to 12 ounces.
76 ounces is equal to 4 pounds and 12 ounces.
To convert 76 ounces to pounds and ounces, we need to consider that 1 pound is equal to 16 ounces.
Here's how to proceed:
Divide the total number of ounces by 16 to find the number of pounds:
76 ounces ÷ 16 ounces/pound = 4.75 pounds
Since 4 pounds = 4 x 16 pounce/ pound
= 64 ounces ,we subtract this amount from the total of 76 ounces to determine the remaining ounces:
= 76 ounces - 64 ounces
= 12 ounces
Therefore, 76 ounces is equal to 4 pounds and 12 ounces.
