What is the value of x??

6

Step-by-step explanation:

Because they give you a 60 degree angle and a right angle, we know this is a 30 60 90 triangle. Because of the properties of a 30 60 90 triangle, we know that if the shortest side (the bottom) is referred to as b, the hypotenuse will be 2 times the value of b (2b) and the side x would be b times the square root of 3. To solve this you would divide 12 by 2 to get b, which would be 6. To get the side you're solving for, x, you would then multiply 6 by the square root of 3. this is your answer.

b) 1/3 * 1/5

step-by-step explanation:

each smallest part is 1/15 since the written one is 1/5 and it's divided by 3 equal parts. (1/5 )/3 = 1/15 = 1/3 * 1/5
