Simplify by combing like terms to get 2x+5
The answers would be:
the coefficient is 2
the constant is 5
There are two terms.
Answer:
Explanation:
In a right triangle the angle between the hypotenuse and the adjacent leg to the angle are related by the trigonometric ratio cosine.
Cosine is the ratio of the adjacent leg to the hypotenuse:
In the right triangle ART, AT is the hypotenuse, AR is the ajacent leg to the angle 66º, and RT is the opposite leg to the angle 66º.
Then, the length of AT and 12.5 is related by the cosine ratio:
Multiplying both sides of the equation by 12.5in:
← answer
1 and 2
because you can do the math and it works:
1+2=3
1*2=2
Price of 3 shirts=$18*3=$54
Price of 2 pair of socks=2*$3.99=$7.98
Price of a pair of slack=$45
Total amount- $54+$7.98+ $45-$106.98
Sales tax rate = 8.5%
8.5% of total amount-8.5% of $106.98=
(8.5/100)*106.98-9.0933
Total amount Rick paid=$106.98+9.0933=$116.0733

Answer:
See attached for the cyclic quadrilateral
To prove: <BAD + <BCD =180°
Construction: Join B and D to the centre O of circle ABCD
Proof
With the lettering of the attached drawing,
<BOD = 2y (angle at centre is 2 X angle at circumference)
Reflex <BOD = 2x (angle at centre is 2 X angle at circumference)
∴ 2x + 2y = 360° (angle at point)
∴ x + y = 180°
∴ <BAD + <BCD = 180°
Step-by-step explanation:
The vertices of a cyclic quadrilateral lie on the circumference of the circle and the opposite angles of a cyclic quadrilateral lie in opposite segment of a circle.
The question is to prove that the opposite angles of a cyclic quadrilateral are supplementary that is 180°. Another way of stating this theory is 'Angles in opposite segments are supplementary'.
Note that the sum of supplementary angles is 180°.
