First you must remember that: An isosceles triangle consists of a vertex angle and 2 CONGRUENT base angles.
subtract 180-24

CHECK:
25+78+78=180
Answer: 1372 Square meters
Step-by-step explanation:
7*14+28*14+7*14+7*28+14*28+7*28=1372
X=y+3
<span>-5x-4y=<span>30
-------------------
Substitute y + 3 for x in </span></span>-5x-4y=30
<span><span>-5<span>(y+3)-</span></span>4y</span>=<span>30
</span>-9y-15=<span>30
</span>----------------------------
Add 15 to each side
<span><span>-9y-15</span>+15</span>=<span>30+<span>15
-9y = 45
</span></span>-----------------------------------
Divide each side by -9
-9y ÷ -9 = 45 ÷ -9
y = -5
Now we solve for x
====================================================================
Substitute -5 for y in x = y + 3
x=-<span><span>5</span>+<span>3
</span></span>x = -2
----------------------
(-2,-5) is your answer
Answer:
B
Step-by-step explanation:
m(slope) = y2 - y1 / x2 - x1
