PLZ I NEED HELP UNDERSTANDING THIS SOMEONE PLZ HELP ME
tatuchka [14]

Answer:

90

Step-by-step explanation:

180°-104°=76°( sum of angles A and B)

76°÷2=38°

x=38°

Bcuz it is an isosceles triangle ( a triangle with 2 equal sides). So, angle B and A are equal. thats why 76° must be divided by 2.

180°-104°=76°(angles on a straight line)

180°-76°=104° (sum of angle A and C)

104°÷2=52°

y=52°

it is also an isosceles triangle.

x+y=38+52=90°

Which expression has the sum of twenty six twentieths? (4 points) Selected:a. two fifths plus four tenthsThis answer is incorrec
patriot [66]

Answer: b. four fifths plus two fourths

Step-by-step explanation: Change the fractions to their equivalents in 20ths-- like finding the common denominator.

Divide the original denominator into 20, then multiply the result by the original numerator to get the new numerator.

4/5  <em>20/5 = 4    4×4 = 16   so 4/5 is equivalent to 16/20</em>

2/4   <em>20/4 = 5    5×2 = 10   so  2/4 is equivalent to 10/20   </em>

Add:    16/20 + 10/20 = 26/20
