20% decrease

1400 ÷ 100 = 14 (1% of the original)

1400 - 1120 = 280 (difference)

280 ÷14 = 20

it's a percentage decrease because the amount is smaller than the original

In this triangle, what is the value of X?

vovangra [49]

Answer:

The measure of angle x is $26.1\°$

Step-by-step explanation:

we know that

In the right triangle of the figure, the tangent of angle x is equal to divide the opposite side to angle x by the adjacent side to angle x

so

$tan(x)=\frac{26}{53}$

$x=arctan(\frac{26}{53})=26.1\°$

The perimeter of a isclose triangle is 24in and the length of the side is 4 in find the 2 other sides

Scrat [10]

Answer:

10 inches

Step-by-step explanation:

Given

Shape: Isosceles Triangle

$Perimeter=24\ in$

$Side = 4\ in$

Required

Find the length of the other two sides

Represent the other sides with x.

Since it is an isosceles triangle, 2 sides are equal.

So, we have:

$x + x + 4 = 24$

$2x + 4 = 24$

Collect Like Terms

$2x = 24-4$

$2x = 20$

Divide both sides by 2

$\frac{2x}{2} = \frac{20}{2}$

$x = \frac{20}{2}$

$x = 10$

<em>The other sides are 10in each</em>

What is the length of the missing leg? If necessary, round to the nearest tenth.

BabaBlast [244]

<u>Answer:</u>

The length of the hypotenuse is 40 mm.

<u>Step-by-step explanation:</u>

<em>We can solve for 'a' using Pythagoras theorem. Let's solve it.</em>

10² = 5² + a²
=> 100 = 25 + a²
=> a² = 75
=> a = 8.660
=> a = 8.7

Hence, the length of the hypotenuse is 8.7 m.

Hoped this helped.
