In ABC, m∠A=10 and m∠B=145. Select the triangles that are similar to ABC.

Tanya [424]

Answer:

Step-by-step explanation:

A triangle has 180 degrees.

So, 10 + 145 + x = 180

x = 25

This means that the angles in the triangle are:

10, 145, and 25

Using this information, only A has the same values so it is the answer

Shino says the formula to calculate the volume of the prism is V=Bh where B is the area of the base.Angelo says the formula is V

Kruka [31]

Answer:

it depends

Step-by-step explanation:

<em>Shino's formula will work for any prism</em>.

Angelo's formula will work for any prism whose base area can be found by ...

B = (1/2)ew

<em>Angelo can use this formula for a triangular prism</em>.

For a triangular prism, both may be correct.

For a prism of another shape, Shino is correct. (Angelo may also be correct, depending on the variable definitions.)

(7 x 10 ^5) + (4 x 10 ^2)

spayn [35]

$\huge\text{Hey there!}$

$\mathsf{(7\times 10^5) + (4 \times 10^2)}\\\mathsf{= 7\times 10^5 + 4 \times 10^2}$

$\large\textsf{Let's solve for the LEFT SIDE first}$

$\mathsf{7\times 10^5}\\\\\mathsf{10^5}\\\mathsf{= 10\times10\times10\times10\times10}\\\mathsf{= 100 \times 100\times 10}\\\mathsf{= 10,000 \times 10}\\\mathsf{= 100,000}\\\\\mathsf{7\times100,000}\\\mathsf{= 700,000}$

$\large\textsf{NEW EQUATION: }\bold{700,000} + {4}\times 10^2$

$\large\textsf{Now, let's solve for the RIGHT SIDE last}$

$\mathsf{4\times 10^2}\\\\\mathsf{10^2}\\\mathsf{= 10\times10}\\\mathsf{= 100}\\\\\mathsf{4\times100}\\\mathsf{= 400}$

$\large\text{NEW EQUATION: 700,000 + \bf 400}$

$\large\text{700,000 + 400}\\\\\large\text{SIMPLIFY IT!}\\\\\large\text{= 700,400}$

$\huge\text{Therefore, the answer should be: \boxed{\mathsf{700,400}}}\huge\checkmark$
