Please please help me on how to do congruent figures!

Mathematics
1 answer:
AlexFokin [52]2 years ago
7 0

Answer:

x = 5

Step-by-step explanation:

Since both triangles are similar hence;

m<CAB = m<CDE

Given theta

m<CAB = 50degrees

m<CDE = 10x

Substitute the given angles

50 = 10x

Swap

10x = 50

Divide both sides by 10

10x/10 = 50/10

x = 5

Hence the value of x is 5

Solve the following equation for g: 2(g - h) = b + 4
DaniilM [7]

Answer:

g = \frac{b+4+2h}{2}

Step-by-step explanation:

Given

2(g - h) = b + 4 ← distribute parenthesis on left side

2g - 2h = b + 4 ( add 2h to both sides )

2g = b + 4 + 2h ( divide both sides by 2 )

g = \frac{b+4+2h}{2}

Can someone tell me if these answers are right or not? These problems are getting on my nerves!
Bond [772]
1a. 3^1 / 3^2 = 3^1-2 = 3^-1 = 1/3^1 = 1/3.
2b. 4^2 / 4^4 = 4^2-4 = 4^-2 = 1/4^2.
3c. 6^3/6^5 = 6^3-5 = 6^-2 = 1/6^2.
4d. 3^-5 • 3^2 = 3^-10 = 1/3^10.

I believe for the last question its asking only to rewrite exponent as a positive exponent similar to the first question.

Area between two shapes. Geometry IXL pls help !
uysha [10]

Answer:

The answer to your question is A = 441.50 km²

Step-by-step explanation:

Data

Big triangle           Small triangle

base = 33 km       base = 19 km

height = 40 km     height = 23 km

Process

1.- Calculate the area of the big triangle

Area = base x height / 2

Substitution

Area = 33 x 40 / 2

        = 1320 / 2

        = 660 km²

2.- Calculate the area of the small triangle

Area = 19 x 23 / 2

        = 437 / 2

        = 218.5 km²

3.- Subtract the small area to the big area

Share area = 660 - 218.5

                 = 441.50 km²

(8.08×10^-10)÷(4.0×10^-3) in scientific notation?
saw5 [17]

Answer:

\large\boxed{2.02\times10^{-7}}

Step-by-step explanation:

The scientific notation:

a\cdot10^k\\\\1\leq a

We have:

(8.08\times10^{-10})\div(4.0\times10^{-3})\\\\=\dfrac{8.08\times10^{-10}}{4.0\times10^{-3}}\\\\=\dfrac{8.08}{4}\times\dfrac{10^{-10}}{10^{-3}}\qquad\text{use}\ \dfrac{a^n}{a^m}=a^{n-m}\\\\=2.02\times10^{-10-(-3)}\\\\=2.02\times10^{-7}
