Answer:

The angle x° = 34°

Step-by-step explanation:

Given the right-angled triangle

right angle = 90°

Given the angle = 56°

We know that the sum of angles of a triangle = 180°

90° + 56° + x° = 180°

x° = 180°- 90° - 56°

x° = 34°

Therefore, the angle x° = 34°

The ratio of the angles in a triangle is 2:3:5. Find the measure of each angle. Measurements are all in degrees.

Julli [10]

Angles in a triangle add up to be 180 degrees. 2x+3x+5x= 180
10x=180
x=18
2(18) = 36
3(18) = 54
5(18)= 90

Given a=4, b=-2 and c=8, evaluate a-b-c

atroni [7]

Filling them in it would be ; 4 - (-2) - 8
And a negative against a negative equals a plus so ; 6 - 8 = your answer

The question is asked of the photo

aivan3 [116]

Pythagoras Theorem:
$\boxed { \boxed {a^2 + b^2 = c^2 \beta }}$

Apply Pythagoras Theorem:

a² + 6² = 11²

a² = 11² - 6²

a²= 85

a = √85

a = 9.22 (nearest hundredth)

Answer: RT = 9.22 cm

What is the value of i^20+1?

ICE Princess25 [194]

You know

$i^2=-1$

Squaring both sides gives

$(i^2)^2=(-1)^2\implies i^4=1$

Then raising both sides to any integer power $n$ gives

$(i^4)^n=1^n\implies i^{4n}=1$

That is, any power of $i$ where the power is a multiple of 4 will always be equal to 1.

$i^{20}+1=1+1=2$

But perhaps you mean to write 20+1 as the exponent, in which case

$i^{20+1}=i^{20}i=i$

What’s the answer to this question?

kobusy [5.1K]

The answer is 16.

First of all, you need to divide 4 by 1/4.

4/1 / 1/4 = 1.

15 - 1 + 2

Next, you go from left to right with addition and subtraction, so subtract 1 from 15 first.

15 - 1 = 14

14 + 2

Finally, add 14 and 2.

14 + 2 = 16.
