Answer:

Transformation of ΔABC rotation of 180° about the origin .

Step-by-step explanation:

Given : Coordinates of Δ ABC ,=A ( 3,5) , B( 6,1) , C( 0,1) .

Coordinates of Δ A'B'C' = A' ( -3,-5) , B'(- 6,-1) , C'( 0,-1) .

To find :

Describe the transformation of ΔABC.

Formula used : 180° rotation (clock wise and counter clock wise)

( x , y ) -------> ( -x , -y ).

Solution :

A ( 3,5)-------> A' ( -3,-5).

B( 6,1)---------> B'(- 6,-1).

C( 0,1).---------> C'( 0,-1) .

Therefore, the transformation of ΔABC rotation of 180° about the origin .

3+p/2=6 How do I solve this?

Diano4ka-milaya [45]

$\boxed{\underline{\bf \: ANSWER}}$

$\sf\frac { 3 + p } { 2 } = 6 \\$

Multiply both sides by 2.

$\sf \: 3+p=6\times 2$

Multiply 6 and 2 to get 12.

$\sf \: 3+p=12$

Subtract 3 from both sides.

$\sf \: p=12-3$

Subtract 3 from 12 to get 9.

$\boxed{\bf \: p=9}$

What is the slope of y=-1/2x+3

user100 [1]

Answer:

slope = - $\frac{1}{2}$

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

y = - $\frac{1}{2}$ x + 3 ← is in slope- intercept form

with slope m = - $\frac{1}{2}$

Two angles are supplementary, and one angle is one-fifth the other. Find the measure of the two angles.

choli [55]

:Two Angles are Supplementary when they add up to 180 degrees. Notice that together they make a straight angle.

and if that doesn't help

:There are in an angle of one fifth of the supplementary angle. Supplementary angle decides the angle to always be and the complementary angle is always (i.e., right angle)

Solve the triangle. Round your answers to the nearest tenth.

wel

Answer:

m∠A ≈ 43°

m∠B ≈ 55°

mBC ≈ 20

Step-by-step explanation:

Law of Sines: $\frac{a}{sinA} =\frac{b}{sinB} =\frac{c}{sinC}$

Step 1: Find m∠B

$\frac{29}{sin82} =\frac{24}{sinB}$

Step 2: Solve for ∠B

29sinB = 24sin82°

sinB = 24sin82°/29

B = sin⁻¹(24sin82°/29)

B = 55.038°

Step 3: Find m∠A

180 - (55.038 + 82)

180 - 137.038

m∠A = 42.962°

Step 4: Find BC

$\frac{29}{sin82} =\frac{BC}{sin42.962}$

Step 5: Solve for BC

29sin42.962° = BCsin82°

BC = 29sin42.962°/sin82°

BC = 19.9581
