Explanation:
The triangle is right angled.
The formula for area of the triangle:

base = 3
height = 4
substitute the values:
Answer:
37.5
Step-by-step explanation:
180-75 = 105
180 is the sum of all the angle in a triangle
180-105 = 75
75/2 = x becuz the triangle is icoceles
=37/5
Hope this helps :) Giving me brainiest would help a lot :))
3x2+4x=2
6+4x=2
-6 -6
4x=-4
4 4
x=-1
Answer:
B. y= 1/2 x - 3
Step-by-step explanation:
base equation: y= mx+ b
slope(m) equation:
y2= -1 y1= -3
x2= 4 x1= 0

y- intercept: -3
found by taking the y from (0,-3)
Answer:
y2=-8x is what's graphed so B.
