Since you know that the angles in a triangle add up to 180°, you can solve for x by making it an equation:
2x + x + 14 + x - 38 = 180
4x - 24 = 180
+ 24
4x = 204
÷ 4
x = 51
Now you can substitute x in to the angles
51 × 2 = 102°
51 + 14 = 65°
51 - 38 = 13°
I hope this helps!

First you would need to solve x.
2x+x+14+x-38=180
4x-24=180
4x=204
x=51
Now plug in the x for all three angle measures.
2(51)=102 degrees
51+14=65 degrees
51-38=13 degrees
Final answer is 102 degrees, 65 degrees, 13 degrees

Write an equation of a circle that is centered at (1,-4) with a radius of 10.

alexdok [17]

Answer:

$(x-1)^2 + (y+4)^2 = 100\\\\$

=====================================================

Work Shown:

$(x-h)^2 + (y-k)^2 = r^2\\\\(x-1)^2 + (y-(-4))^2 = 10^2\\\\(x-1)^2 + (y+4)^2 = 100\\\\$

You could expand terms out and simplify, but I think it's more handy to leave it in this form so you can easily spot the center and radius from a glance.

. Harold works at a men's clothing store, which marks up its retail clothing by 27%. The store purchases pants for $74.00, suit

Paraphin [41]

Answer:

567.69

Step-by-step explanation:

Let p represent the original price

The Mark up is 27%

= 27/100

= 0.27

= p + 0.27p

= 1.27p

The retail price for pants is

= 1.27(74)

= 93.98

The retail price for suit jacket is

= 1.27(325)

= 412.75

The retail price for dress shirt is

= 1.27(48)

= 60.96

Therefore the markup for a pair of pants, dress shirts and suit jacket can be calculated as follows

= 93.98 + 412.75 + 60.96

= 567.69

The sides of a rectangle are in the ratio 2:5. The perimeter of the rectangle is 70 cm. What is the width of the rectangle?

EleoNora [17]

Width = 10cm

Length = 25cm

<u>Explanation: </u>

Given, width:length = 2:5

Let width = 2x ,

So, length = 5x

Perimeter of rectangle = 2x(length + width)

According to the question,

$70cm = 2X(5x + 2x)\\70cm = 2X(7x)\\35cm = 7x\\x = 5cm$

Hence,

Width = 10cm

Length = 25cm
