Is college math a lot of triangles? ( please answer)

A triangle is a three-sided figure whose angles always add up to 180°. Thus, ∠x +∠y + ∠z = 180°.

The largest angle of a triangle is opposite its longest side.

On the SAT, the triangle to the left would be referred to as triangle abc or ∆abc.

To find the perimeter of the triangle, add up all the sides (a + b + c).

To find the area of any triangle, use the formula, (1⁄2)bh. The height must be perpendicular to the base.

Two triangles are similar if their angles have the same measure. The triangles therefore have the same shape, and their sides will be in proportion.

Triangles are said to be congruent if they have the same shape and size.

Equilateral Triangles

Equilateral Triangle

An equilateral triangle has three equal sides. Thus: a = b = c.

An equilateral triangle has three angles are also equal. Thus, ∠x = ∠y = ∠z.

Since the angles of a triangle always add up to 180°, each angle of an equilateral triangle must also equal 60°. Thus, ∠x = ∠y = ∠z = 60°.

Step-by-step explanation:

the answer is (-8,-5)

step-by-step explanation:

the endpoint to midpoint is half the length. the length is (-2,-1) so when you are at the midpoint just add it to it to find your answer -6+(-2)= -8 and -4+(-1)=-5 so (-8,-5)

third choice down

step-by-step explanation:

the first inequality is based on the number of adults and campers, and the second inequality is based on the cost of feeding both the adult and the camper.

we know that there is room for 525 people max.   it's ok to have less than 525, but it's not ok to have more than 525, so the inequality is less than or equal to.   the number combination of adults (x) and campers (y) cannot exceed this 525 max.   therefore:

x + y ≤ 525

now we talk about cost.   it costs $9 to feed one adult, so depending upon the number of adults you have (x) depends upon how much it will cost to feed that number of adults.   same with the campers, who cost $5 to feed.   the adults can be represented by 9x and the campers can be represented by 5y.   since the budget cannot exceed 1,200, the second inequality is:

9x + 5y ≤ 1200
