Work out the size of angle A.
А
11 cm
9 cm
38°
B.
С

There are two solutions!

a = 48.80524 degrees

or

a = 131.19476 degrees

Step-by-step explanation:

A = sin^-1 (sinB * 1/b) = sin^-1 * (sin(38degrees) * 11/9. =.    sin^-1 (0.75)

^ is used to signify to the __ power

I do not have the proper options for some mathematical functions on my device I’m answering from

option c) graph of line going through 1, 4 and 3, 10

step-by-step explanation:

let y equal to margo's coin collection

let x equal to number of years

at the begining x=0, y=1 → point=(x,y)→point=(0,1)

she adds 3 coins per year, then y=1+3x

at x=1, y=1+3(1)=1+3→y=4→point=(x,y)→point=(1,4)

at x=3, y=1+3(3)=1+9→y=10→point=(x,y)→point=(3,10)

the graph of line going through (1, 4) and (3, 10), then the option c is the correct.
