Mathematics
1 answer:
Georgia [21]3 years ago
4 0

Answer: The missing angle is 13°

Step-by-step explanation:

Let ∠B

be the missing angle.

Let ∠A

be the angle that measures

77∘Let ∠C

the right angle that measures

90∘

The following is true of all triangles:

∠A+∠B+∠C=180∘

Express the above equation as

∠B

in terms of the other angles:

∠B=180∘−∠A−∠C

Substitute the values for ∠A and ∠C

∠B=180∘−77∘−90∘

∠B=13∘

What is a 3, 4, 5 triangle?
Alexandra [31]

Answer:

<em>A special right triangle is a right triangle with some regular feature that makes calculations on the triangle easier, or for which simple formulas exist. For example, a right triangle may have angles that form simple relationships, such as 45°–45°–90°. This is called an "angle-based" right triangle.</em>

Step-by-step explanation:

Hope this helps

mercury : 5.8 • 107 = 620.6
Venus : 1.1 • 108 =118.8

620.6 - 118.8 = 501.8

James is hosting a game show where a contestant has to draw a ball that is one of four colors from a pot. Each day, a ball of a
Rashid [163]
Let the number of red, black, green and blue balls be R, B, G, U respectively.

B=R  (There are as many black balls as red balls)

G+R=10 so G=10-R (Green balls and red balls should add up to 10)

R+10=U (There should be 10 more blue balls than red balls)

The minimal number of balls is 2, 304 so we have the following inequality:

R+B+G+U≥ 2,304

R+(R)+(10-R)+ (R+10)≥2,304

4R≥2,304

R≥2,304/4=576 so R=576
