Answer:

b.) Triangle 7 has a 40 degree angle and a 35 degree angle. Triangle 8 has a 40 degree angle and a 105 degree angle.

Step-by-step explanation:

b.) triangle 7's 3 angles: 40° , 35° and 180° - 40° - 35° = 105°

    triangle 8: 40° , 105° and 180° - 40° - 105° = 35°

they have all 3 corresponding angles congruent, triangle and triangle 8 is similar (AAA)

Answer:

b.) Triangles 7 and 8 are similar.

Step-by-step explanation:

If triangles have the same angle measurements, they are similar

If we have two angles, we can find the third by using the equation 180 (total of all angles in any triangle) - angle 1 -angle 2 = angle 3.

Let's set up this value with values from triangle 7.

180-40-35=angle 3

105=angle 3

Thus, the angle measurements of triangle 7 are 35, 40, anf 105.

Let's set up the same equation with value for triangle 8.

180-40-105=angle 3

35=angle 3

Thus, the angle measurements of triangle 8 are 35, 40, anf 105, the same as those of triangle 7, meaning the two triangles are similar.

How can a rational number and irrational number when multiplied together make a irrational number ?
pochemuha

Answer:

"The product of a rational number and an irrational number is SOMETIMES irrational." If you multiply any irrational number by the rational number zero, the result will be zero, which is rational. Any other situation, however, of a rational times an irrational will be irrational

A better statement would be:

"The product of a non-zero rational number and an irrational number is irrational
