The flag of a country contains an isosceles triangle.​ (Recall that an isosceles triangle contains two angles with the same​ mea
weeeeeb [17]

31 degrees, 31 degrees, 118 degrees

Step-by-step explanation:

Step 1 :

Let x be the measure of 2 angles of the given isosceles triangle with same measure

Let y be the measure of  3rd angle

So we have x + x + y = 180

Step 2 :

Given that the measure of  3rd angle of  triangle is 25​° more than three times the measure of either of the other two​ angles

So we have , y = 3 x + 25

Step 3:

Substituting for y in the first equation we have,

x + x + 3 x + 25 = 180

=> 5 x + 25 = 180

=> 5 x = 180-25 = 155

=> x = 155/5 = 31

Hence the 2 angles of the triangle are 31 degrees.

Step 4:

we have y = 3 x + 25

=> y = 3 * 31 + 25 = 118

Hence the 3rd angle of given triangle is 118 degrees

The domain for variables x and y is the set {1, 2, 3}. The table below gives the values of P(x, y) for every pair of elements fr
Olin [163]

Answer:

Option B and C are correct answers.

Step-by-step explanation:

Option B and C are the correct options.

Option a is true since row 1 has all T.

so for X=1, P(x,y) is true for all y.

Option b is false since no column has all F.

Option C is false since no column has all F.

Option D is true since 1st row has all T.

hence option B and C are correct answers.

How do i estimate quotients 933 divided by 3
Maurinko [17]
K, so
remember that \frac{a+b+c}{d} = \frac{a}{d}+ \frac{b}{d}+ \frac{c}{d}
so
\frac{933}{3}=\frac{900+30+3}{3} = \frac{900}{3}+ \frac{30}{3}+ \frac{3}{3}   = 300+10+1=311
