Answer:
The expression Riley could have used to find the product of the two numbers is 24 × (30 + 7).
Step-by-step explanation:
The distribution property for multiplication is:

In this case we need to determine the product of 37 and 24.
Compute the product as follows:


Thus, the product of 37 and 24 is 888.
Uhhh I think the last one but there is fraction calculator on safari if you want to use it. Sorry
X = 35°
y = 45°
the angle of x is congruent to 35°, meaning their measurements are equal. and to find y, you must remember that all the angles in a triangle sum to 180°. so, you just need to add 35° and 100°, giving you 135°. from there, you subtract it from 180° and get 45°
i hope this makes sense!!
