-2x + 6 - 13x + 16
= -15x + 22
Answer:
Step-by-step explanation:
So you can use the special formula for 30-60-90 triangle or you can use the whole Soh Cah Toa thing.
I honestly prefer trig. so a is the opposite side of the 30 deg and 12 is the hyp. This should scream sine to you since sine goes with opposite/hypotenuse.
sin(30 deg)=a/12
Multiply both sides by 12
giving a=12 sin(30)
Type into calculator unless you know your unit circle well.
a=6
Answer:
See below, there may be more than one answer
Step-by-step explanation:
4(3+1)+2 = 18
(4+2)(3)+1 = 19
(1)(2+3)(4) = 20
(1+2)(3+4) = 21
Answer:
(c)=81°, a=9.1, b=12.
Step-by-step explanation:
m<A=40°, m<B=59
m<C=180-(40+59)=81
c=14
I think its 32 minus 16 which is 16, dont forget to label!
