Y= X - 5
The y-intercept is is 5 and the slope is 1 because it moves up one up and one right.
Problem 1
We're given that angle A = angle B. Also that angle B = angle C.
By the transitive property, we can say angle A = angle C.
So basically all three angles are equal to one another. Let's call that unknown angle x.
For any triangle, the three angles always add to 180, so,
x+x+x = 180
3x = 180
x = 180/3
x = 60
That proves angles A,B, and C are each 60 degrees. This triangle is considered equiangular since all angles are the same. Furthermore, the triangle is also considered equilateral meaning all sides are the same. The term equilateral is more widely used, so I'd go with that term if you could only pick one.
==========================================================
Problem 2
As mentioned in problem 1, the three angles of a triangle add to 180
A+B+C = 180
A+B+90 = 180
A+B+90-90 = 180-90
A+B = 90
This shows A and B are complementary angles. Complementary angles by definition add to 90 degrees.
Can you be more specific pls
You're welcome and don't mention it, beforehand.
There's so little to this problem, and it will do you so much
more good to work it out yourself, that I'm just going to
point you in the right direction and give you a little push:
The area of a triangle is half of the product of its base and height.
A = (1/2) (base) (height)
I know you know what the base and height are, because
you just told them to US.
Base = 7.5m = 750 cm
Height = 6 cm.
Write those numbers in the formula in place of the words:
<span> A = (1/2) (base) (height)</span>
A = (1/2) (750 cm) (6 cm) .
Do that multiplication, and you've got your area.
Don't forget to keep the units when you multiply,
so that the answer is in units of cm² .
The answer may be a big number, and you may want to
change it to meter² instead of cm², to make it a smaller
number.
If you do that, remember that
1 meter = 100 cm
1 meter² = (1 meter) · (1 meter)
= (100 cm) · (100 cm)
= 10,000 cm²
