Step-by-step explanation:
sum of the ratio=3+3+4=10
now,
angle I = 3/10×180=54
angle II= 3/10×180=54
angle III=4/10×180=72
that shows th given triangle is isoceles
Answer:
-11
Step-by-step explanation:
-8x+5-3x-4+5x x=2
-8*2+5-3*2-4+5*2
-16+5-6-4+10
-11-6-4+10
-17-4+10
-21+10
-11
Answer:
(3x-7)(3x+7)
Step-by-step explanation:
3^2 * x^2 -7^2 (expand that out)
(3x)^2 - 7^2
(3x-7)*(3x+7)
x+2=5y / 3y=12 / 2y=x+2z are essentially your equations
from the 2nd one, 3y=12, we know y=4, or in your case, circle = 4
we can then plug 4 into x+2=5y to get x+2=20, or x=18, which means diamond = 18
then, plug 4 and 18 into 2y=x+2z for 2(4)=18+2z / 8=18+2z / -10=2z / -5=z, so triangle = -5
