Answer:

SAS

Step-by-step explanation:

Consider triangles ABC and DEF. In these triangles,

AC ≅ FD;
AB ≅ DE;
∠A ≅ ∠D (included angle).

Thus, by SAS postulate, triangles ABC and DEF are congruent.

The Side Angle Side postulate (SAS) states that if two sides and the included angle of one triangle are congruent to two sides and the included angle of another triangle, then these two triangles are congruent.

The population of a city has increased by 36% since it was last measured. If the current population is 51000 , what was the prev

PilotLPTM [1.2K]

So if we have the number after the 36% increase in population, we would want to subtract that 36% from 51000.

36% of 51000 can be found by multiplying 51000 by 0.36 (0.36 is the decimal equivalent of 36%)

51000 x .36 = 18360

So you simply subtract 18360 from 51000, which is 32,640.

Find the measure of each bolded arc. Round to the nearest hundredth

vladimir1956 [14]

Answer:

Arc Length = 68.7

Step-by-step explanation:

The formula that is used to find the arc length:

s = (θ/360) * 2πr

(You would get the value of θ, by subtracting 57 from 360)

(You would get r by dividing 26 by 2)

Now we can solve this;

s = (303/360) 2π(13)

s = 0.842 * 2π(13)

s = 0.842 * 0.283(13)

s = 68.7

Hope this helps!
