Lesechka [4]

Answer:

65 degrees

Step-by-step explanation:

An exterior angle form a linear pair with an interior angle.

A linear pair of angles must add up to 180 degrees

180-115 = 65

The number of three-digit numbers with distinct digits that can be formed using the digits 1, 2, 3, 5, 8, and 9 is . The probabi

Tems11 [23]

Answer:

1/15

Step-by-step explanation:

When we form such three-digit numbers with distinct digits using the digits 1 , 2 , 3 , 5 , 8 and 9 (in all six digits all different), observe that the order of digits does matter. For example, if we make a number using digits 1 , 2 , and 3 , we can have 123 , 132 , 231 , 213 , 312 or 321 .

Hence we have to find number of 3 digit numbers that can be made from these six digits using permutation and answer is ⁶ P ₃ = 6 × 5 × 4 = 120 .

.How haw many of them will have first digit as even, we have two choices 2 and 8 . Once we have chosen 2

for hundreds place, we can have only 8 in units place and any one of remaining 4 can be used in tens place. Hence four choices, with 2 in hundreds place and another four choices when we have 8 in hundreds place (and 2 in units place) i.e. total 8 possibilities.

Hence, the probability, that both the first digit and the last digit of the three digit number are even numbers, is 8 /120 = 1 /15

How could you graph an inequality like this x>3?

Firlakuza [10]

Answer:

see below

Step-by-step explanation:

The graph of it on a number line is an open circle at x=3 with a line extending to the right through larger numbers.

When the inequality does not include the "or equal to" case, the boundary is graphed as a dashed line (on an x-y plane) or open circle (on a number line). The shaded area covers values of the variable that meet the condition of the inequality. Here, those are values of x that are more than 3.

A triangle has sides with length of 11 feet 12 feet and 13 feet. Is it a right triangle

krek1111 [17]

Answer:

Step-by-step explanation:

It will be a right triangle if it follows Pyhthagoras Theorem . Where the sum of squares of two smaller sides is equal to the square of the 3rd side. Let's check ,

→ 11²+ 12² = 13²

→ 121 + 144 = 169

→ 265 ≠ 169

<h3>Hence the ∆ is not a right angled triangle </h3>
