Step-by-step explanation:
in the given figure ,
the two sides of the triangle are equal , so their opposite angles are equal .
so , we get
=》Angle RPQ = Angle PRQ = 65°
and some of interior angels of the triangle measures 180°
so,
=》RPQ + PRQ + RQP = 180°
=》65° + 65° + RQP = 180°
(Because RPQ = PRQ = 65°)
=》130° + RQP = 180°
=》RQP = 50°
Answer:
Step-by-step explanation :
Ratio = 3x : 4x
<h3>
Sum of angle of a quadrilateral = 360</h3><h3>
Therefore, 140+80+3x+4x = 360</h3><h3>
220+7x = 360</h3><h3>
7x = 360-220</h3><h3>
x= 140/7</h3><h3>
x=20</h3><h3>
3x= 3×20=60</h3><h3>
4x=4×20=80</h3>
Jenny does, she bakes 12 for every x and dan bakes 10 for every x.
So in conclusion jenny bakes more cookies per batch
Answer:
Step-by-step explanation:
we know that
To find the ratio of yellow to red marbles, divide the numbers of yellow marbles by the number of red marbles
Let
x-----> the numbers of yellow marbles
y----> he number of red marbles
we have
