Answer:

60 degrees

Step-by-step explanation:

BWA is an isosceles triangle, meaning that BW and WA are equal in length.

Thus, we have that ABW and WAB are congruent to each other.

ABC is a complementary angle, so ABW and CBD add up to 90 degrees.

ABW is 30 degrees, so we have 30 degrees+ CBD=90 degrees.

Subtracting thirty degrees from both sides we get CBD=60 degrees.

Hope this helps!

Frankie earns $5 each time he babysits his little sister. He has saved $30. Frankie wants to save $52 to buy a new skateboard. W

inessss [21]

Answer:

Frankie will need to babysit for 4.4 time.

Step-by-step explanation:

We are given the following in the question:

Money earned by Frankie each times he babysits = $5

Money saved = $30

Total money Frankie wants to save for a skateboard = $52

Amount of money to be saved =

Total amount of money Frankie wants to save for a skateboard - Money saved already

$= 52-30\\=22\$$

He needs to save $22 more.

Let x be the number of times Frankie will need to babysit.

Thus, we can write the equation:

$5x = 22\\\\\Rightarrow x = \dfrac{22}{5}\\\\\Rightarrow x = 4.4$

Thus, Frankie will need to babysit for 4.4 time.

Answer:

Cube=150cm^2

Triangular Prism=228ft^2

Step-by-step explanation:

Cube

$A=6a^2=6*5^2=150cm^2$

Triangular prism

Using these formulas

$A=2A_{B}+(a+b+c)h\\A_{B} =\sqrt{s(s*a)(s*b)(s*c)} \\s=\frac{a+b+c}{2}$

Solving for A

$A=ah+bh+ch+\frac{1}{2} \sqrt{-a^4+2(ab)^2+2(ac)^2-b^4+2(bc)^2-c^4} \\=6.5*11+5*11+6.5*11+\frac{1}{2} *\sqrt{-6.5^4+2*(6.5*5)^2+2*(6.5*6.5)^2-5^4+2*(5*6.5)^2-6.5^4} \\=228ft^2$
