Answer:

A=35, B=55, and C=25

Step-by-step explanation:

Angle A and the angle next to it are linear pairs, so you can subtract 145 from 180.

if you already know Angle A, and that the other angle is 90 degress, you can add 90+35 and subtract it from 180 to get Angle B

Angle C is paired with the angle across from it (I forgot what the term is called) so it is 25 degrees.

find the distance between the two given points. O(-3,-2) and P(-3,4)​

Answers

Answer:

[tex]\boxed {\boxed {\sf d= 6}}[/tex]

Step-by-step explanation:

Distance can be found using this formula:

[tex]d=\sqrt {(x_2-x_1)^2+(y_2-y_1)^2[/tex]

Where (x₁, y₁) and (x₂, y₂) are the points.

We are given the points O (-3, -2) and P(-3,4). Therefore,

[tex]x_1= -3 \\y_1= -2 \\x_2= -3 \\y_2=4[/tex]

Substitute the values into the formula.

[tex]d=\sqrt {(-3--3)^2+(4--2)^2[/tex]

Solve according to PEMDAS: Parentheses, Exponents, Multiplication, Division, Addition and Subtraction.

Solve inside the parentheses first.

(-3--3)= -3+3=0(4--2)= 4+2=6

[tex]d= \sqrt {(0)^2+ (6)^2}[/tex]

Solve the exponents.

(0)²= 0*0=0 (6)²= 6*6=36

[tex]d=\sqrt {0+36[/tex]

Add.

[tex]d= \sqrt {36[/tex]

Take the square root.

[tex]d=6[/tex]

The distance is 6.

Answer:

The measure of the largest triangle is 72.

Step-by-step explanation:

Set up an equation to find the angle. note that angles in a triangle sum to 180.

With this information, we can set up an equation:

24x + 21x + 15x = 180

(add the x terms)

60x = 180

(divide both sides by 60)

x = 3

We now know what x equals. Now, we can multiply 3 by the largest angle of all- 24.

24 * 3 = 60.

Thats the question asked by scientists who studied a mass die-off of turkeys in Great Britain. It turned out that all the turkeys had eaten peanuts from Brazil. A fungus was growing on the peanuts. The fungus produced a dangerous poison called aflatoxin. Aflatoxins cause stomach pain, lung failure, cancer, and death in people and animals.Farmers make a great effort to prevent fungi from growing on their stored crops. In a pile of grain or nuts, fungi have plenty of food and living space. The best way for farmers to prevent fungi from growing is to make sure there is not enough for fungi to survive and grow.
