Answer:
320
Step-by-step explanation:
5, 20, 80,5,20,80,5, comma, 20, comma, 80, comma is not a geometric sequence.
However, if you mean 5, 20, 80 it is a geometric sequence.
It is being multiplyed by 4 each time
so 80*4=320
The next number would be 320.
Given:
Radius of circle is 13 cm
Height of triangle is 5 cm
To find:
Value of 'a' and 'b'
Steps:
To find value of 'a', we will use Pythagoras theorem as the triangle is a right angle triangle,
A² + B² = C²






Now to find the value of 'b', i will use law of cosine,


Therefore, the values of 'a' and 'b' is 12 and 67.38 respectively

Answer:
73
Step-by-step explanation:
Since DA is the diameter, this means that you can divide the circle into two half-circles. You will solve with the right half-circle. A half-circle has a 180 total degrees. Add up the values given and solve for x.
(2x) + (7x - 4) + (85) = 180
2x + 7x - 4 + 85 = 180
9x - 4 + 85 = 180
9x + 81 = 180
9x = 99
x = 11
Now that you have the value of x, solve for m∠CZB.
m∠CZB = 7x - 4
m∠CZB = 7(11) - 4
m∠CZB = 77 - 4
m∠CZB = 73
