Pls help w these thx <33
stepladder [879]

Answer:

36.81233927

13.02532494

Step-by-step explanation:

You need to use the law of sine for both of them

the law of sine is as follows:

\frac{a}{\sin(A)}=\frac{b}{\sin(B)}=\frac{c}{\sin(C)}

Question 1:

\frac{15}{\sin(64)}=\frac{10}{\sin(y)}\\y=36.81233927

Question 2:

Let x= AB

Start by solving for the missing angle, 53

\frac{8.4}{\sin(31)}=\frac{x}{\sin(53)}

x= 13.02532494

I will leave you to round the answers

A phone company charges $0.06 per minute for local calls and $0.15 per minute for international calls. When your bill comes, it
solmaris [256]
Let's assume two variables x and y which represent the local and international calls respectively. 

x + y = 852 = total number of minutes which were consumed by the company (equation 1)
0.06*x+ 0.15 y =69.84 = total price which was charged for the phone calls (Equation 2)
 from equation 1:-
x=852 -y (sub in equation 2)
0.06 (852 - y) + 0.15 y =69.84

51.12 -0.06 y +0.15 y =69.84 (subtracting both sides by 51.12)
0.09 y =18.74
y= 208 minutes = international minutes (sub in 1) 
208+x=852 (By subtracting both sides by 208)
x = 852-208 = 644 minutes = local minutes

Can someone please help me.
Natasha2012 [34]

Answer:10√2

Step-by-step explanation:

∆ABC is a right angle triangle

Angle A + Angle B + angle C = 180

There angel B = 180-135= 45

Angle A = Angle B

Therefore AC= BC=10

By Pythagoras ppt AB^2=10^2 +10^2

=100+100

=√200

=10√2

2 2/3× 4 1/5 help me plzzzzz!!!
Rus_ich [418]
First let's multiply the whole numbers 2 and 4. Obviously that is 8. Now let's put aside the whole number and multiply fractions.

2/3 x 1/5 is equal to 2x1/3x5 so it's 2/15 which is already in simplest form. 

So your final answer is 8 and 2/15 :)

If this was helpful would you mind marking mine as brainliest please? It helps me rank up a lot!
