Step-by-step explanation:
Opposite angles in a cyclic quadrilateral are supplementary.
Therefore 3c = 4d = 180°, c = 60° and d = 45°.
Y= 3x - 10
<span>3x + 2y = 16
3x+2(3x-10)=16
3x+6x-20=16
9x-20=16
9x=36
x=4
y=3x-10
y=3(4)-10
y=12-10
y=2</span>
Answer would be #9 .hourses
Answer:
the number is 21
Step-by-step explanation:
(9+x)(4)=120
9+x=30
x=21
Answer:
Yes
Step-by-step explanation:
The definition of a rational number is a number that can be represented as a fraction. Since 56/7 is a fraction it must be a rational number. An irrational number is a number that cannot be represented as a fraction because it never ends and repeats without a pattern forever. An example of this is pi because pi can never exactly be represented as a fraction.
