Answer:
Here is the answer.
x= 1/2(7+3i√3) and 1/2(7-3i√3)
Answer: m∠2 = 160°, m∠3 = 20°.
Step-by-Step Explanation: We know that m∠1 = 160°.
The values of both m∠1 and m∠2 are equivalent, which means that m∠2 is also 160°. The interior angles of a rhombus always add up to 360°, and when we add both 1 & 2, we get 320°.
The <em>other</em> opposite ends of a rhombus's interior measures are also the same in value. ... To figure out what m∠3 is, let's do the following steps:
1. 360-320 = 40
This means that the remaining two angle measurements will add up to 40°.
2. 40/2 = 20.
The final missing angle; m∠3 = 20°.
3. There, done!! Good luck!

(A) Find the value of x. Round to the nearest tenth of a degree<span>
Given that the distance of the ground is 9ft.
Length of the plank is 41 ft
In order to get the angle formed between the ground and the foot of the plank,
cos (theta) = ground / plank
cos (theta) = 9 / 41
</span><span>cos (theta) = 0.21951...
</span>theta = cos^-1(<span>0.21951...)
</span><span>theta = 77.3 degrees
</span><span>(b) Find the height above the ground where the plank touches the wall. Round to the nearest tenth of a foot.
</span><span>
Height = square root (plank^2 - ground^2)
Height = square root (41^2 - 8^2)
</span><span>Height = square root (1600)
</span><span>Height = 40
(A) 77.1 Degrees
(B) 40 feet</span>
Answer:
is there supossed to be a picture?
Step-by-step explanation:
The class needs to sell at least 20 tickets
Let x be the number of tickets that need to be sold in order to add up to $1000
Using the equation $700+$15x>=$1000
Subtract 700 from both sides and then divide each side by 15 to get 20.
