Answer:
1= perimeter, 2=area, 3=neither, 4=perimeter, 5=neither, 6=neither
Step-by-step explanation:
I think these are all the right answers, tell me if they're not.
As in this figure two sides of triangle are equal so angle A=B because angle opposite to equal sides are equal so
60+x+x= 180
60+2x=180
2x= 180-60
2x=120
x=120/2
x=60
Therefore B,C is 60
Answer:
4
Step-by-step explanation:
you need 4 halves to make 2 whole!
Use tangent
tan=opposite/adjacent
tan(54)=x/150
multiply by 150
150×tan(54)=x
206.5=x (approximately)
Answer:
I believe it is -123
Step-by-step explanation:
you have to replace all the x's with -4 so you would do the equation -6(-4)^2+8(-4)+5
-6(-4)^2 is -96
-96+8(-4) is -128
-128+5 is -123
