In the triangle 30 - 60 - 90 the sides are in the ratio 1 : √3 : 2 (look at the picture).

So, we have a = 3, and x = a√3.

Your answer is x = 3√3 (3sqrt(3))

In an honors math class of 25 students, 15 are boys and 10 are girls. On the final exam, 6 boys and 3 girls received a grade of

postnew [5]

Answer:

Step-by-step explanation:

b=boy

a= a on the exam

b=15

b∩a=6

b'∩a=3

b'∪a'=?

b'∪a'= b'+a'-b'∩a'

a= b∩a+b'∩a (law of total probability) = 9

a'= 25-9 = 16

b'= 25-15= 10

16+10-7=19

19/25= .76

M is between points C and Q. CM=17 and CQ=21. What is MQ?

katrin2010 [14]

Sometimes it helps to draw it out...

(17)
C_______M_________Q
|___________________|
21

therefore, CM + MQ = CQ
17 + MQ = 21
MQ = 21 - 17
MQ = 4 <===

Answer:

V = 16
W = 48

Step-by-step explanation:

The triangles are congruent when corresponding sides are congruent.

ΔFGH ≅ ΔABC means corresponding sides are ...

(GH, BC) = (V, 16)

(HF, CA) = (48, W)

Corresponding sides being congruent means ...

V = 16

W = 48
