Answer:

Say something along the lines of ¨This triangle is not a right triangle because it has no right angles, instead it is an isosceles triangle. This is because it has 2 sides that are perfectly equal. It also can be obtuse or acute because it has no obtuse/acute angles. This triangle also has two equal angles (A and C) these angles are the smaller angles. The angle B is a big angle so B+A+C=180 degrees.¨

Guys need help its surd one <br><img src="https://tex.z-dn.net/?f=5%20%5Csqrt%7B3%20%5Cdiv%202%20%5Csqrt%7B3%20-%20%20%5Csqrt%7B

Answer:

Step-by-step explanation:

$\displaystyle \Large \boldsymbol{} 5\cdot \sqrt{3:2\sqrt{3-\sqrt{2} } } =\\\\\\ 5\cdot \sqrt{\frac{3}{2\sqrt{3-\sqrt{2} } } \cdot \frac{2\sqrt{3+\sqrt{2} } }{2\sqrt{3+\sqrt{2} } } } = \\\\\\5\cdot \sqrt{\frac{6\sqrt{3+\sqrt{2} } }{4\cdot \sqrt{9-2} } } =5\sqrt{\frac{6\sqrt{3+\sqrt{2} } }{2\sqrt{7} } }$

But if the condition would be like this

$\displaystyle \Large \boldsymbol{} 5\cdot \sqrt{3:2\sqrt{3-\boldsymbol2\sqrt{2} } } =\\\\\\5\cdot \sqrt{\frac{3}{2\cdot \sqrt{\underbrace{2+1-2\sqrt{2} \cdot \sqrt{1} }_{(\sqrt{2} -1)^2} } }} =\\\\\\5\cdot \sqrt{\frac{3}{2\cdot (\sqrt{2}-1) } } } = \\\\\\ 5\cdot \sqrt{\frac{3}{2(\sqrt{2}-1 )} \cdot \frac{\sqrt{2} +1}{\sqrt{2}+1 }} =5 \sqrt{\frac{3}{2(2-1)} } =\boxed{5\sqrt{1,5} }$

Five times a number which is 3 more than h. Write this as an expression.

ladessa [460]

｡☆✼★ ━━━━━━━━━━━━━━ ☾

So, let's start off with h

The expression needs to be '3 more than h'

This can be written as:

h + 3

The expression also needs to be 'five times' this value

This can be written as:

5(h + 3)

That would be your answer ^^

Have A Nice Day ❤

Marta is making a scale drawing of her apartment for a school project. The apartment is 28ft wide. On her drawing, the apartment

ivolga24 [154]

Answer:

<h2>The scale is 1 inch rep 4 feet or </h2><h2>1:4</h2>

Step-by-step explanation:

This problem is on ratios, the ratio of one quantity to another is a way to represent their relative size.

Moreso, the scale of a drawing tells us to what extent the drawing has been increased (maximized) or decresed (minimized)

now given that the actual dimention of the appartmentis 28ft wide

and on the drawing the apartment is 7 inches wide, we can see that the actual dimension has been reduced by a factor of 28/7= 4

hence the scale to represent this reduction is

1 inch to represent 4 feet
