Answer:
(b) 36 degrees.
Step-by-step explanation:
K is the center of the circle so triangle KMN is isosceles and m < KMN = m KNM = 26 degrees ( base angles are equal)
So m < LMK = m <LMN - m < KMN
= 98 - 26
= 72 degrees.
Now triangle LKM is also isosceles since K is the center of the circle so
m < LKM = 180 - 2* 72
= 180 - 144
= 36 degrees.
Answer:
3/4=63/84
66.66%=56/84
5/7=60/84
⇒66.66%; 5/7; 3/4
Step-by-step explanation:
Answer:
convert the expression for N into logs
evaluate those logs using a log table
thus determine log N
calculate antilog of log N

Call one of the angles = x
The other one is 180 - x
They are in the ratio of 3 to 5
Equation
3/5 = x / (180 - x)
Solve
3/5 = x / (180 - x) Cross Multiply
3*(180 - x) = 5x
540 - 3x = 5x Add 3x to both sixes
540 = 5x + 3x
540 = 8x
Divide both sides by 8
540 / 8 = x
x = 67.5
One angle is 67.5
The supplement is 180 - 67.5 = 112.5
Check
67.5/112.5 = 0.6 which is the same thing as 3/5
