Answer:
M = 8.85
Step-by-step explanation:
10 - 1.15 = 8.85
A=-10 all you do to find a is simply add 2 to both sides of the equal sign
Answer:
The answer is 2
Step-by-step explanation:
sin60°+ 2 tan45° - cos30°
sin60° = √3/2
2 tan45° = 1
cos30° = √3/2
sin60°+ 2 tan45° - cos30°
√3/2 + 2(1) - √3/2
√3/2 - √3/2 + 2(1)
0 + 2 = 2
Thus, The answer is 2

Answer:
D) 111
Step-by-step explanation:
In order to find ∠KJH we must find the measure of arc KH
Note that ∠KJH is a central angle and arc KH is the arc it intercepts
Because ∠KJH is a central angle it equal the measure of its intercepted arc
Thus, ∠KJH = arc KH
J is a circle that is made up of 3 arc; KL, LH and KH
If you didn't know the sum of the arcs in a circle = 360°
Which means that arc KL + arc LH + arc KH = 360
If arc KL = 136 and arc LH = 113
Then 136 + 113 + arc KH = 360
^ ( note that we just created an equation that we can use to
solve for arc KH )
We now solve for arc KH
136 + 113 + arc KH = 360
* combine like terms *
136 + 113 = 249
we now have 249 + arc KH = 360
* subtract 249 from each side *
249 - 249 cancels out
360 - 249 = 111
We're left with arc KH = 111°
Like stated previously arc KH = ∠KJH
Hence, ∠KJH = 111°
