Answer:
Step-by-step explanation:
y=mx+b
8=-7m+b
2=0m+b
subtract
6=-7m
-6/7=m
2=0m+b
2=b
y=-6/7x+2
change to standard from
y+6/7x=2
Answer:
Step-by-step explanation:
Sin58 = opp/hyp
Sin58 = CB/14
CB = 14 × sin58°
CB = 11.9cm
Answer:
e) 1.7%
Step-by-step explanation:
1 / 58 = 0.017
0.017 * 100 = 1.7
Answer:
C) a = 10√3, b = 5√3, c = 15 , d = 5
Step-by-step explanation:
Here we use the ratio of 30, 60, 90 degree triangle.
The ratio of sides, 1:√3:2
2x = 10
x = 5
d = 5
b = 5√3
c = 5√3√3
c = 5*3 = 15
c = 15
a = 2(5√3)
a = 10√3
Therefore, a = 10√3, b = 5√3, c = 15 and d = 5
