Answer:

answer of 11

Step-by-step explanation:

given A=30°

R.H.S=2sinA cosA

=2 * sin30° * cos30°

2  \times \frac{1}{2}  \times  \frac{ \sqrt{3} }{2}

= \frac{  \sqrt{3} }{2}

=sin60°

sin 2*30°

=sin2A

L.H.S=R.H.S

Solve for the value of x
viva [34]

Answer:

x=9

Step-by-step explanation:

To solve for x, you can set up a proportion between the 2 triangles we see.

The small triangle can be written as \frac{16}{20}, and the large triangle can be written as \frac{16+12}{20+2x-3} = \frac{28}{2x+17}.

Set both proportions equal to each other.

\frac{16}{20}=\frac{28}{2x+17}

Cross multiply and solve for x.

16(2x+17)=(28)(20)

32x+272=560

32x=288

x=9

A player made 24 out of 40 free throws. What is the probability that the player will make her next free throw?
nikitadnepr [17]
So basically, the player made 24 out of 40 free throws, which means that she had gotten 60% of her shots so far. I'm assuming that this means that she has a 60% chance of getting it in next time.

A 2-digit number with x units and 7 less units than tens.
Hatshy [7]
Each two digit number has two numbers (duh!). Let's allow the tens digit to be x and the units digit to be y. Tens digit is 3 less than the units digit: x = y-3 Original number is 6 more than 4 times the sum of the digits: 10x+y-6 = 4x + 4y This gives us simultaneous equations!First let's clear the mess: 1. x= y-32. 6x-3y=6 Substitute 1 into 2: 6(y-3) -3y =66y - 18 - 3y = 6
 3y = 24y = 8 Our units digit is 8 Substitute y= 8 into 1. x = y - 3x = 5 Our tens digit is 5 Therefore, our number is 58
