The answer is 40°
i will tell you how,
Total angle sum of any triangle is 180°
∠A + ∠B  + ∠E = 180°
70° + 80° + ∠E = 180°
solve for ∠E
∠E = 30°
Now solve use ∠BDE,
∠B + ∠D + ∠E = 180°
20° + 90° + 30° + x = 180°           (in triangle DEB, ∠E = 30 + x ) (∠D is 90°)
solve for x
there fore, x = 40°

Carrie has 3 times as many green beads as red beads and 2 as many blue beads as green beads if she has 150 total how many green
Vikentia [17]

There are 45 green beads

<em><u>Solution:</u></em>

Let the number of red beads be "x"

Given that, Carrie has 3 times as many green beads as red beads

Number of green beads = 3 times number of red beads

Number of green beads = 3x

<em><u>She 2 as many blue beads as green beads</u></em>

Number of blue beads = 2 times the number of green beads

Number of blue beads = 2(3x) = 6x

<em><u>She has 150 total</u></em>

Therefore,

Number of red beads + Number of green beads + Number of blue beads = 150

x + 3x + 6x = 150

10x = 150

x = 15

Thus, number of green beads = 3x = 3(15) = 45

Thus there are 45 green beads
