The answer is (A) SSS. The triangles share one side and it is indicated that the other two are congruent.
Answer:
the ratio of the surface area of Pyramid A to Pyramid B is:
Step-by-step explanation:
Given the information:
- Pyramid A : 648
- Pyramid B : 1,029
- Pyramid A and Pyramid B are similar
As we know that:
If two solids are similar, then the ratio of their volumes is equal to the cube
of the ratio of their corresponding linear measures.
<=> = = =
<=>
Howver, If two solids are similar, then the
n ratio of their surface areas is equal to the square of the ratio of their corresponding linear measures
<=>
=
So the ratio of the surface area of Pyramid A to Pyramid B is:
Subtract the expression on the right of the equal sign. Collect terms. (Write the exponent properly.)
.. x² -9x +20 = 0
The third angle of the triangle is 72 degrees, if that’s what your looking for
1.y=-7x-2
2.y=-4x+10
next time juust plug the numberes in for example for the first one right the y=mx+b then plug in 5 for the y and -1 for the x then -7 for the m then solve
