Your numbers are -2 and -7 and here's how you find them: a + b = -9 b = -9 - a b = (-9 - a) [We have now found the value of b in terms of a.] a - b = 5 a - (-9 -a) = 5 a +9 + a = 5 2a + 9 = 5 2a = -4 a = -2 [We have solved for a, and now we substitute that back in to solve for b.] a + b = -9 -2 + b = -9 b = -7 [And now we've solved for b, the second unknown, and solved our problem.]
The sum of all interior angles of a polygon with n sides is 180 degrees × (n - 2), so the sum of all angles within a pentagon is 540 degrees (180 x (5 - 2) = 180 x 3 = 540). The five interior angles of a pentagon then must have an average of 108 degrees each (540 / 5 = 180), and the angles having consecutive integers will be 106, 107, 108, 109, and 110 degrees. The largest angle will be 110 degrees.
5 degrees angle, because the sum of two complementary angles is 90 degrees.
No because to form a triangle the sum of its two smaller sides must be greater than its longest side
The perimeter is the sum of the four sides. In this case, two sides have 14 cm each, and the other two sides have 5 cm eacn.
A convex figure has eight sides. What is the sum of its exterior angles?
The integers are -7 and -5.
-3, 5
The numbers -2 and -7 add together to make -9, and their difference is 5.
5 + (-3) = 2 5 - (-3) = 8 The two numbers are therefore 5 and -3.
5 & 10
-4 and -5
10
-4 and -1
To find the sum of two integers with different signs, you simply combine them, and give the result the sign of the larger integer. For example, you have two integers: -9 and +5. You combine them, that is the +5 cancels out 5 of the -9, leaving -4.
It need not be. 2 and 3 are consecutive integers and their sum is 5, not 31.
-2 and 5
The two consecutive negative odd integers having 74 as the sum of their squares are -5 and -7.
