Answer:
B. m∠RTS = 78°
Step-by-step explanation:
The sides GH and GI of ΔGHI have the same length, so their opposite angles, ∠I and ∠H will have the same measures. Call that measure "x".
The sum of angles in a triangle is 180°, so we have ...
24° +x +x = 180°
2x = 156° . . . . subtract 24°
x = 78° . . . . . . divide by 2
The triangle similarity statement tells you that ∠T will have the same measure as ∠I, which is x, or 78°.
m∠RTS = 78°
A student says that the measures of coterminal angles are never opposites of each other, the student is wrong because Coterminal angles are angles in standard position (angleswith the initial side on the positive x -axis) that have a common terminal side. For example 30° , −330° and 390° are all coterminal.
120 groups <span>(10*9*8/3*2*1=120) </span>of 3 (k) operators are possible to make from the 10 (n) qualified employees. This problem can be solved using the combination formula in mathematics which is to find the possible number of combination (group of operator) from a set of choices. (Formula : n*(n-1)*...* (n-k+1)/ k!).
3 1
---- = -----
15 5
12 1*12 1
---- = -------- = -----
60 5*12 5
so from these above wrote result that these fractions are equals
hope helped
