Syd chooses two different primes, both of which are greater than $10,$ and multiplies them. The resulting product is less than $

Mars2501 [29]

Answer:

Step-by-step explanation:

There are 7 primes between 10 and 35: 11, 13, 17, 19, 23, 29, 31.

The product of 11 and any of the others will be less than 350, 6 products.

The product of 13 and any below 26 will be less than 350, 3 more products.

The product of 17 and any below 20 will be less than 350, 1 more product.

There are a total of 10 different products below 350 possible.

Answer:

See below.

Step-by-step explanation:

From the given info the 2 triangles are isosceles with AE = FR and ET = RP because the 2 sets of base angles are equal.

As the base angles are congruent m < E = m < R.

So the are 2 triangles are congruent by SAS, ASA and AAS.
