ABC is a right-angled triangle.
AC= 16cm
Angle c= 90• (degrees)
Size of angle b: size of angle A = 3:2
Work out the length of AB
Give your answer to 3 significant figures.

Step-by-step explanation:

step 1

Find the measure of angle A

we know that

Triangle ABC is a right triangle

so

The sum of angle A plus angle B must be equal to 90 degrees by complementary angles

----> equation A

so

----> equation B

substitute equation B in equation A

solve for A

step 2

Find the length of side AB (hypotenuse)

we know that

----> by CAH (adjacent side divided by the hypotenuse)

substitute the given values

b. y = 4x - 2

step-by-step explanation:

to find a parallel equation to an equation, make sure both equations have the same slope but different y-intercepts.

y = 4x + 1

4 = slope

1 = y-intercept

y = 4x - 2

4 = slope

-2 = y-intercept

they both have the same slope but different y-intercepts, so, b. is the correct answer.

and to check your work, you can graph both equations. : )

60.9774

step-by-step explanation:

because when you add 47.6 plus 7.32 equals 54.92

and when you add .0574 + 6= 6.0574

and when you add 54.92 and 6.0574 you get the answer of 60.9774.
