Angle A and angle B are congruent, because they are on a line, and if the middle angle is in the middle, then the two outer angles would be congruent.
Hope this helps! :)
Answer:
The first triangle.
Step-by-step explanation:
SAS is Side-Angle-Side. It means that we have two sides of one triangle congruent to the corresponding two sides of the other triangle, and the included angle of the first triangle congruent to the corresponding included angle of the second triangle.
In the first triangle, the base sides are marked congruent. The side that connects the triangles is congruent to itself. This is two sides; the right angle falls between them, making it the included angle. This is SAS.
Answer:
it has no solution
Step-by-step explanation:
first of all if we want to know that how many solutions does it the system we can know easly
- if a1/a2=b1/b2=c1/c2 then the system has infinite solution
- if a1/a2=b1/b2≠c1/c2 the system has no solution
- if a1/a2≠b1/b2 the system has no solution
so in this system a1=2,a2=4,b1=3,b2=6,c1=4&c2=4
so 2/4_3/6_4/4=(to becomfortable to compare we have to find the denominators LCM.LCM(4,6)=12
6/12=6/12≠12/12.
so the system has no solution.
&you can also solve by this way
2x+3y=4 (multiply by ‒2 to be y=0)
4x+6y=4
‒4x‒6y=‒8
4x+6y=4
= 0+0=‒4(error)
so it has no solution
i think it is clear & i hope it helps you.
Answer:
405π
Step-by-step explanation:
Use the formula for Volume Of Cylinder (V=πr²h) where "V" represents the volume, "r" represents the radius, and "h" represents the height
<u>The volume and the radius are given. (V=45π, r=3)</u>
<u>1. Solve for height</u>
V=πr²h
45π=π3²h
45π/π=3²h
45=3²h
45=9h
45/9=h
h=5
<u>2. Plug the new radius (3*3=9) into this formula and solve for "V"</u>
V=π9²5
V=π81*5
V=405π
NEW VOLUME AFTER A TRIPLED RADIUS IS 405π
