This one is easy.
<span>–8.6 = –4.1 + x
</span>
So, what you have to do is add 4.1 on both sides.
You do this because you want to get X alone. when you do,
-8.6+4.1=-4.5
X=-4.5
The answer is B
Answer:
Complement: 55°
Supplement: 145°
Step-by-step explanation:
<em>Complementary </em>angles are any two angles which sum to 90° (a right angle); <em>supplementary </em>angles sum to 180° (a straight angle).
35 + 55 = 90, so 55° is the <em>complement </em>to 35°, while 145° is the <em>supplement, </em>since 35 + 145 = 180.
You have to calculate the air, a=h*b/2 so the answer is d)
The LCD is 30.
Think of it this way. You and I are on an assembly line checking i-pads. Your job is to quality check every 6th one and my job is to check every 10th one.
Here are the ones you will check:
6, 12, 18, 24, 30 and so on
Here are the ones I will check
10, 20 30 and so on.
Notice the first one we both check? #30 - that is the LCD of 6 and 10
m∠H = 50°
∠H is a inscribed angle, and so that the intercepted arc would be twice the amount of the angle.
Arc KI = 100°
Because ∠KGI & ∠HKI share the same arc, the measurement for ∠KGI will be the same as ∠HKI, or 50°
m∠KGI = 50°
Next, find m∠KJI. arcKJI = 2(∠H) = 2(50) = 100
m∠KJI = 100°
