Answer:
A = 20 degree
B = 160 degree
C = 160 degree
D = 20 degree
Step-by-step explanation:
If the measure of angle C is eight timeseight times the measure of angle A
That means C = 8A
But According to the question, angles A and D have the same measure as well as angles C and B.
That is, B = 8A and D = A
If A + B + C + D = 360
Let us substitute for B, C and D
A + 8A + 8A + A = 360
18A = 360
A = 360/18 = 20
Therefore
A = 20 degree
B = 8 × 20 = 160 degree
C = 8× 20 = 160 degree
D = 20 degree
5 : 7
Marbles : Stones
35/5 = 7
So stones
= 7 * 7
49
=35 : 49
If x =-3 that means the equation becomes
Y=2(-3) +1 and when you simplify you get
Y=-5 hope this helps :)
Answer:
Step-by-step explanation:
Use the cosine rule and see if the numbers hold true. a^2 = b^2 + c^2 - (2bc (cos x))
By substituting in our values I get that cos x = 0.838... which is possible. If cos x would equal 1.5, the there is no solution and the triangle would not be possible.
