Using pythagorean theorem, you can find the hypothesis of one triangle.
2^2+b^2=4^2
4+b^2=16
b^2=14
take the square root and you would get b=3.7
After, you would do the same thing, except use 3 for A.
3^2+x^2=3.7^2
9+x^2=13.69
x^2=4.96
take the square root and get x=2.2

Plzz any help please​
butalik [34]

Answer:

9

Step-by-step explanation:

If the sine of an angle is equal to the cosine of an angle, that means that the sides adjacent and opposite to that angle are equal. One triangle that has two equal sides is an isosceles triangle. We can set this triangle to be a 45-45-90 degree triangle, which means that the angle would be 45.

Now, we have to find the value of

4\tan^2(45)

and

5\tan(45)

The tangent of 45 is 1, so 1 squared times 4 is 4.

We have 4\tan^2(45) = 4.

Again, the tangent of 45 is 1, and 1 times 5 is 5.

We have 5\tan(45) = 5

5 + 4 = 9

HREE 8. I invest £x at 3% per annum and £y at 4% per annum. My annual income from these investments is £22. Had I invested £y at
inna [77]

Answer:

x = £200

(y = £400)

Step-by-step explanation:

Convert interest rates into decimal format:

3% = 3/100 = 0.03

4% = 4/100 = 0.04

From information given, create 2 equations:

0.03x + 0.04y = 22

0.04x + 0.03y = 20

Rearrange equation 1 to make y the subject:

⇒ 0.03x + 0.04y = 22

⇒ 0.04y = 22 - 0.03x

⇒ y = 550 - 0.75x

Substitute y = 550 - 0.75x into equation 2 and solve for x:

⇒ 0.04x + 0.03(550 - 0.75x) = 20

⇒ 0.04x + 16.5 - 0.0225x = 20

⇒ 0.0175x = 3.5

⇒ x = 200

To find y, substitute found value of x into one of the equations and solve for y:

⇒ 0.04(200) + 0.03y = 20

⇒ 8 + 0.03y = 20

⇒ 0.03y = 12

⇒ y = 400
