Answer:
2/5
Step-by-step explanation:
The ratio of the two is just the numbers divided. The ratio of the newer computer to the older computer is 0.2/0.5, which is the same as 2/5.
Area of circle is πr^2
<u>Here</u>,
• π = 3.14
• d = 10
• so, r = d/2 = 10/2 = 5
<u>substituting the values in the formula,</u>
Area = 3.14 x 5 x 5
Area = 3.14 x 25
Area = 78.5 m^2
Hence, option (c) is correct.
x = 45°
Solution:
Given data:
Measure of larger arc = 152°
Measure of smaller arc = 62°
<em>If a tangent and a secant intersect at the exterior of a circle then the measure of angle formed is one-half the positive difference of the measures of the intercepted arcs.</em>
⇒ x = 45°
The value of x is 45°.
Answer:
-2.44
Step-by-step explanation:
Is a right angle triangle
We apply SOHCAHTOA
SOH is sin=Opposite divided by Hypotenuse
CAH is cos=Adjacent divided by Hypotenuse
TOA is tan=Opposite divided by Adjacent
so in this case,cos is the right thing to use
Therefore,x=adjacent
15=Hypotenuse
angle=52°
Cos(52)=x÷15
making x the subject,
x=15cos(52)
x= -2.44
