Hello,
sin B/b=sin C/c
==>sin B=√3 / 2 * 6/8=3√3 /8
Answer:
Option B, 1
Step-by-step explanation:
tan 45° = 1/1 = 1
We are given
△ABC, m∠A=60° m∠C=45°, AB=8
Firstly, we will find all angles and sides
Calculation of angle B:
we know that sum of all angles is 180
m∠A+ m∠B+m∠C=180
we can plug values
60°+ m∠B+45°=180
m∠B=75°
Calculation of BC:
we can use law of sines

now, we can plug values



Calculation of AC:

now, we can plug values



Perimeter:

we can plug values


Area:
we can use formula

now, we can plug values

Answer:
2 and -3
Step-by-step explanation:
because a coefficient is a numerical or constant quantity placed before and multiplying the variable in an algebraic expression (e.g. 4 in 4x).
so in 2x-3y+5, 2 and -3 are the coefficients.
