Let x be the bigger angle
y the smaller angle
x + y = 18 <span>supplementary
</span>
x = 5y
we replace quation 2 in equation 1 so
5 y +y =180
6y = 180
y= 30
and x= 5y = 5*30 = 150
Answer:
x = 75°
y = 105°
Step-by-step explanation:
Angle subtended on the circumference of the circle is half of the angle subtended on the center of the circle.
Quadrilateral PQRS is a cyclic quadrilateral.
Answer:
Option B:
Step-by-step explanation:
The parabola has its concavity downwards, so we need a function in the model:
With a negative value of 'a'
The vertex is (0,0), so we have that:
The x-coordinate of the vertex is given by the equation:
So we have a function in the model:
With a < 0
The only option with this format is B:
The answer is the first one , A
Answer:
31
Step-by-step explanation:
3 times 2 is 6, plus 1 is 7
7 times 2 is 14, plus 1 is 15
15 times 2 is 30, plus 1 is 31
31 times 2 is 62, plus 1 is 63
63 times 2 is 126, plus one is 127
