Solve the right triangle, ΔABC, for the missing sides and angle to the nearest tenth given angle B = 27° and side c = 15.
nignag [31]

Answer:

Part 1) C=90\°

Part 2) A=63\°

Part 3) b=6.8\ units

Part 4) a=13.4\ units

Step-by-step explanation:

step 1

Find the measure of angle C

we know that

The triangle ABC is a right triangle

so

Angle C is a right angle

therefore

C=90\°

step 2

Fin the measure of angle A

we know that

In the right triangle ABC

∠B+∠A=90° -----> by complementary angles

we have

B=27\°

substitute

27\°+A=90\°

A=63\°

step 3

Find the length side b

we know that

In the right triangle ABC

sin(B)=b/c

b=(c)sin(B)

substitute the given values

b=(15)sin(27\°)=6.8\ units

step 4

Find the length side a

we know that

In the right triangle ABC

sin(A)=a/c

a=(c)sin(A)

substitute the given values

a=(15)sin(63\°)=13.4\ units

Write an equation of the line in slope-intercept form that passes through the point (-6, 1) and has a slope of ½.
snow_tiger [21]

Answer:

  y = 1/2x +4

Step-by-step explanation:

You are given the slope (m) of the line and a point, and asked for slope-intercept form:

  y = mx +b . . . . . . . line with slope m and y-intercept b

The value of the intercept, b, can be found from the point by rearranging this equation to ...

  b = y -mx

  b = 1 -1/2(-6) = 4 . . . . using x=-6, y=1

Then the equation of the line with m=1/2 and b=4 is ...

  y = 1/2x +4

valina [46]

Answer:

8x=96 inch

Step-by-step explanation:

How its in the draw you have this situation then the equation that model is the next one:

2*(3X) + 2*X = 96 inch

6X + 2X = 96 inch

8X=96 inch

We must multiply due that there is two sides that measure the same.
