A certain triangle has a 30° angle in a 60° angle. Which must be a true statement about the triangle
Lady bird [3.3K]

Answer:

It is a right triangle.

Step-by-step explanation:

A right triangle is a triangle with at least one angle with 90 degrees.

We know that every triangle has 180 degrees. The other unknown angle is 180 - (30+60) = 180 - 90 = 90. That means that the other angle is 90 degrees. Therefore, it is a right triangle

We also know that in this triangle, that the square of one side plus the square of another is side is equal to the square of the hypotenuse of the triangle. (According to Pythagorean theorem)

1. Solve proportion 12/15 = 18/b
omeli [17]
We solve the as follows:

<span>1. Solve proportion 12/15 = 18/b
</span>( 12/15 = 18/b ) b<span>
( 12b/15 = 18 ) 15/12
b = 18(15/12)
b = 45/2

2. Solve equations 

A. -x + 4 = x +6 
</span>-x + 4 - x = x +6 - x
<span>-2x + 4 - 4 = 6 - 4
-2x = 2
x = -1

B. 5n + 7 =7(n+1) -2n 
5n + 7 = 7n + 7 - 2n
5n -7n + 2n = 7 - 7
0 = 0

C. -4(p+2) + 8 = 2(p-1) - 7p + 15
-4p - 8 + 8 = 2p - 2 - 7p + 15
-4p + 7p - 2p = -2 + 15 + 8 - 8
p =13

3. Solve a/b x - c = 0 for x 
</span>a/b x - c = 0 
( a/b x = c ) b/a
x = bc / a

A citrus grower anticipates a profit of $100,000 this year if the nightly temperatures remain mild. Unfortunately, the weather f
Alchen [17]

Answer:

The grower should spend the $5,000, thereby reducing the profit to $95,000.

But, this is based on a 20% probability of freezing temperature during the next week.

Step-by-step explanation:

A) If freezing weather happens with a 20% chance, the profit will be reduced to $60,000.

With this probability, the probable loss will be 20% X $40,000 = $8,000.

B) If the grower can protect the fruit against freezing weather at a cost of $5,000, then she should go ahead.  Doing this, the profit will be reduced to $95,000 because of the cost.

However, it is worthy to note that freezing weather happens at 20% chance.  This implies that the freezing weather might not happen, 80% chance.  But, prudence still demands that necessary precautions are taken, and this includes protecting the crop at a cost of $5,000.
