180 - 275 = <span>95
</span>Which is... C) 95kg
An easy way to check your answer is right is to add 95 to 180.
180 + 95 = 275
275=275
The answer checks out!
Answer:
A. 76
Step-by-step explanation:
Angle A is half the difference between the measures of arc DE and BC.
m∠A = (1/2)(DE -BC)
20 = (1/2)(116 -BC) . . . . substitute the given values
40 = 116 -BC . . . . . . . . multiply by 2
BC = 116 -40 . . . . . . . . add BC -40
BC = 76

<em>Comment on intersecting secants</em>
When the secants intersect <em>inside</em> the circle, the angle where they cross is half the <em>sum</em> of the intercepted arcs. When they intersect <em>outside</em> the circle (as here), the angle where they meet is half the <em>difference</em> of the intercepted acs.
Sometimes it is easier to remember two related relationships than it is to remember just one of them.
Hi Vance :)
a=leg unknow
b=leg
c=hypotenuse
a²+b²=c²
a²=c²-b²
a²=145² - 144²
a²=21,025 - 20,736
a²=289
a=√289
a=17
unknow leg = 17 units
Answer:
Step-by-step explanation:
Given 
(A) 
We know that Sin(A + B) = SinA cosB + cosAsinB
Substituting in the above formula we get:
(B) Cos(A + B) = CosAcosB - SinASinB
(C) Tan(A + B) = 
From the above obtained values this can be calculated and the value is .
