X=56°
Because cos =90- sin
Perpendicular has slope that multiplies to -1
the slope for ax+by=c is -a/b
-1x+2y=4
slope=-(-1)/2=1/2
1/2 times what=-1?
-2
y=mx+b
m=slope
we need slope is -2
y=-2x+b
find b
given
(-2,1)
(x,y)
x=-2 and y=1 is a solution
1=-2(-2)+b
1=4+b
mius 4 both sides
-3=b
y=-2x-3 is equation
first one
Answer:
Triangle ITA is the answer.
Step-by-step explanation:
<S = <I means that the triangle IRS is an isoscles.
The midpoint (T) cutting both congruent side length sides at the same angle means that Line TG and Line TA are equal.
Also T being the midpoint means Line TI = Line TS.
Given that angles <G and <A are same.
You can use SSA (side-side-angle) to prove triangles are congruent so line SG is equal to Line IA.
The answer is b c=113/10
hope this helps
brainliest is always appreciated :)
