They are both 51. Because m1 is 51, and m3 is as well bc they r opposing or “vertical” angles.
Well I don't know !
Let's count them.
You can get a 5 if the cubes
fall in any one of these ways:
1 . . . 4
2 . . . 3
3 . . . 2
4 . . . 1
That looks like four possibilities.
Can you think of any others that I missed ?
The side lengths are congruent, because the triangle is only being moved
Time used total: 50 hours.W+C = 50 (1) Total water used is 1900 L.Woody family used: 40W; Carter family used 35C.Equation showing how much water both families used:40W + 35 C =1900. (2) We have a system with two equations and two variables. We can use substitution method to solve the system. From equation (1) we express W:W=50 - C. (1a) We substitute the variable in equation (2):40(50 - C) +35C =1900. We open the parenthesis2000 -40C +35C =1900, We combine like terms2000 -5C =1900, We subtract 2000 from both sides of the equation-5C = 1900 - 2000, We simplify-5C = -100, We divide by -5C = 20. We substitute the values of C in the equation (1a) and find the value of W:W = 50 - C,W = 50 -20 =30. The Woody family used water for 30 hours and the Carter family used water for 20 hours.We check our work to be sure we did not make any mistakes:Total water used: 40 x 30 + 35 x 20 = 1200 + 700 = 1900 L.
Answer:
If the angle of vertex of isosceles triangle is 50° then the angle of base is <em><u>8</u></em><em><u>0</u></em><em><u>°</u></em><em><u> </u></em>
Explanation -
Sum of all angles of a triangle is 180°
As we know in an isosceles triangle 2 sides and equal its opposite angles are also equal .
50 + 50 + X = 180
100 + X = 180
X = 180 - 100
X = 80°
