AABC has a >b>c. If one of the angles in the triangle is 60°, name the angle that
Westkost [7]

Answer:

m ∠A =90°, m ∠B =60°, and m ∠C =30°

Step-by-step explanation:

If a > b> c  you know the the side opposite ∠ A is the longest side and the side opposite ∠C is the shortest side.  

side BC is the longest side,  side AB is the shortest side, and side AC measure is the second longest side.    

Draw the Δ ABC and label the longest side, shortest side, and the middle side.  Now the longest side is opposite the biggest angle, the shortest side is opposite the smallest angle.  

m ∠A =90°, m ∠B =60°, and m ∠C =30°

Match each radius or diameter of a circle with its approximate circumference.
jok3333 [9.3K]

Answer:

radius: 3 units <----> Circumference: 18.84 units

Diameter: 12 units <----> Circumference: 37.68 units

Diameter: 36 units <----> Circumference: 113.04 units

Radios: 5 unites <----> Circumference: 31.4 units

Step-by-step explanation:

How I got the answers for the radiuses:

3 (this is only half the diameter so if you do 3 x 2 you will get the diameter.)

3 x 2 = 6

C = pi x d

C = 3.14 x 6

C = 18.84 [this is the first radios]

5 (this is only half the diameter so if you do 5 x 2 you will get the diameter.)

5 x 2 = 10

C = pi x d

C = 3.14 x 10

C = 31.4 [this is the second radios]

How I got the diameters:

12 (this is the full diameter so we do not have to multiply it by 2)

C = pi x d

C = 3.14 x 12

C = 37.68 [this is the first Diameter]

36 (this is the full diameter so we do not have to multiply it by 2)

C = pi x d

C = 3.14 x 36

C = 113.04 [this is the second Diameter]

1<br> 3<br> (<br> x<br> +<br> 1<br> )<br> 2<br> =<br> 15
Gre4nikov [31]

X= - 0.4231

Step-by-step explanation:

Step 1:

The given equation can be expressed as

13*(X+1)*2=15

Here to find the value of X BODMAS rule is applied

BODMAS= Brackets Orders Division Multiplication Addition Subtraction

Step 2:

Expand the given equation

13*2*(X+1)=15

26*(X+1)=15

X+1=15/26

X+1=0.5769

X=0.5769-1

X=-0.4231
