Answer:

Step-by-step explanation:

*this is a 90 degree triangle

so we will use Pythagorean theorem to get X

hypotenuse²=side of right triangle²+the other side of right triangle²

50²=30²+x²

2500=900+X²

2500-900=x²

1600=x²

x=√1600

=40

so the answer is 40

Due in 10 min help! <br> Find t.

lys-0071 [83]

Given:

A right angle triangle with angles 45, 45, 90 degrees.

Hypotenuse of the triangle = $7\sqrt{2}$ mm

Base of the triangle = t

To find:

The value of t.

Solution:

In a right angle triangle,

$\cos \theta=\dfrac{Base}{Hypotenuse}$

Using this trigonometric ratio in the given triangle, we get

$\cos (45^\circ)=\dfrac{t}{7\sqrt{2}}$

$\dfrac{1}{\sqrt{2}}=\dfrac{t}{7\sqrt{2}}$

$\dfrac{7\sqrt{2}}{\sqrt{2}}=t$

$7=t$

Therefore, the value of t is 7 millimetres.

On the horizontal number line show how you will round 198.78 to the tens place & write the rounded number. Given picture is

harkovskaia [24]

If the three slashes are 190, 195, and 200, we can see it as
<span>-l----------l--------|--l- with the slightly longer line being around 198.78. Since it is clearly closer to the end of the line than the start of the line, we round it to 200</span>
