Answer:
First, draw a quadrilateral figure QRST. Then, label angles RST, QST, and QSR.
Given:
mRST = 65
mQST = 2x
mQSR = 3x - 10
From the figure, angle RST is the sum of angles QST and QSR. Therefore:
mRST = mQST + mQSR
Substituting the values, the equation becomes:
65 = 2x + (3x -10)
Solve for x:
x = 15
Second awnser :
Upon drawing the triangles given, it may be observed that they share one common side, ST. Hence, m QSR is the sum of m RST and m QST. Mathematically,
3x - 10 = 65 + 2x
The value of x from the equation generated above is 75. Thus, the answer to the question above is 75.
Hope i got it
Answer:
19,050,000
Step-by-step explanation:
1) Anything after the 10,00 place value turns into a zero
2) Add one more if the 10,000 place value is higher than 5 if not leave it alone
Think of it this way: Lets add numbers in pairs, starting at the very outer 2 numbers (19 and 77) then go in by one and add the second number and the second to last (20 and 76), then (21 and 75) and so on. The sum of all of these pairs are all the same: 96. How many 96s will we have? Well since we're coming from each end toward the middle adding pairs we will have half the distance between 19 and 77, that is (77-19)/2 = 29. So we can actually just take 96*29 = 2784. This is the sum of all numbers between 19 and 77
