Answer:

Step-by-step explanation:

In the triangle, there is a 90 degree angle and Angle 1 (what we are looking for) and the other angle, lets call is Angle 2.

Lets find Angle 2 first.

First of all, the angle between angle 40 and 90 can be found easily.

That angle (lets call it "x) and 40 and 90 make a straight angle (180 degrees). So we can write:

40 + x + 90 = 180

Lets solve for "x":

40 + x + 90 = 180

130 + x = 180

x = 180 - 130

x = 50

Now, This angle (50) and Angle 2 are same [vertical angles]

So,

Angle 2 = 50

Now, there are 180 degrees in 3 angles in a triangle. So for the triangle shown, we cacn write:

90 + Angle 1 + Angle 2 = 180

90 + Angle 1 + 50 = 180

Angle 1 + 140 = 180

Angle 1 = 180 - 140

Angle 1 = 40

A triangle has perimeter 38 cm.

IrinaVladis [17]

Answer:

62cm

Step-by-step explanation:

You were told the perimeter of the triangle is 38

but two sides are added to make a Pentagon. and that Pentagon is made up of a triangle and a square.

so if we find the side of the square, we can equally get the other two sides of the triangle.

hint: (because it's a square, we would be getting an isosceles triangle, meaning two sides are equal)

because one side of the pentagon added to the other two sides of the triangles gives us the perimeter of the triangle.

we first find the sides of the square with all sides equal by diving by 2

$\frac{48}{2} = 12$

the sides of the square making the perimeter of the square 12cm.

now we subtract 12 from the perimeter of the triangle 38

$38 - 12 = 26$

now that we have gotten one side we can get the other two by dividing the result by 2

$\frac{26}{2} = 13$

so the other two sides of the triangle are 13cm.

now since we have the sides of the square and the triangle, we can find the perimeter of the pentagon by adding.

all the sides of the triangle without the base which is also the top of the square.

so instead of adding 4 times of 12, we add 3 times of 12 and 2 times of 13.

3(12)+2(13) = 62

12 + 12 + 12 + 13 + 13 = 62cm

in order to lose 1 pound a person needs to burn about 3,600 more calories than he or she eats and drinks. A person who weighs 15

sattari [20]

Ok so you know that the person burns 3,600 calories in order to lose a pound. If they burn 240 calories per hour, you would just divide 3,600 by 240 to get 15. Since you asked for minutes just multiply by 60 which is 900.
