Answer:

C. Acute; isosceles

Step-by-step explanation:

As you can see 2 sides of the triangle are equal to 10 which means they are congruent. It's an isosceles triangle because it has two congruent sides.

You can also see that none of the angles form 90 degrees or more which means they are acute angles.

Hope that helps

Find the value of the variable and GH if H is between G and I. GI = 5b + 2, HI = 4b – 5, HI = 3

mixas84 [53]

Answer:

Part 1) b=2

Part 2) GH=9 units

Step-by-step explanation:

we know that

If H is between G and I

then

$GI=GH+HI$ -----> by addition segment postulate

Solve for GH

$GH=GI-HI$ -----> equation A

step 1

Find out the value of b

we have

$HI=4b-5\\HI=3$

equate the equations

$4b-5=3$

solve for b

adds 5 both sides

$4b=8$

Divide by 4 both sides

$b=2$

step 2

Find out the value of GH

$GH=GI-HI$

substitute the values

$GH=5b+2-3$

$GH=5b-1$

substitute the value of b

$GH=5(2)-1=9\ units$

Given the equation Y -4 equals three force X +8 in point slope form, identify the equation of the same line in standard form

Genrish500 [490]

Answer:

3x - y = -28

Step-by-step explanation:

Given the equation y-4 = 3(x+8), distribute and simplify to get the Standard Form.

y-4 = 3(x+8)

y - 4 = 3x + 24

y = 3x + 28

-3x + y = 28

Standard form does not allow the coefficient of x to be negative so multiply the equation by -1.

3x - y = -28

3) A rectangular piece of land measures 780 m by 550 m.

marysya [2.9K]

Area = Length x width
A = L x W

a. A = 780 x 550
=429000 m2

b. If 10000m2 = 1 ha
Then 429000 = 429000/10000
= 42.9 ha
