You would use the cosine rule for this as you have 2 lines and are given the angle between them
The angle can be figured out easily as the clock has 12 equal components, meaning each component is 360/12 which is 30
As there are 5 components between A and B the angle is 30*5 =150
You can plug all of this into the cosine rule
a^2= b^2+c^2-2bcCos(A)
So a = sqrt( 10^2 +7^2 -(2*10*7) cos150)
a=16.4 to 3 sf
Answer:
B.) 18
Step-by-step explanation:
90 + 72 = 162
180 - 162 = 18
(90 comes from the right angle)
(72 is already present)
(a triangle adds up to 180 degrees)
Answer: -11
Step-by-step explanation:
five below 0 is -5
6 below -5 is -11
Answer:
Step-by-step explanation:
hello :
y = 4x - 5 means : 4x-y=5
y - 3 = 5(4-X) equivalent : y-3 = 20 -5x means : 5x+y =23
The answer will be number 2
