You cannot memorize a whole multiplication chart in one day, but if you go online and search multiplication stories, there may be some stories to help you memorize your facts quicker depending on your learning style. Also try and remember that any number times any number is just that number being added over and over again a certain amount of times. For example: 3*4= 3+3+3+3 Hope this helps :)
Answer:
48.5 us cups
Step-by-step explanation:
Answer:
We get ∠A =40° and ∠B = 140° and ∠B = 140° is measure of larger angle
Step-by-step explanation:
we have ∠A = (2x − 30)° and ∠B = 4x, and we need to find measure of larger angle. And ∠A and ∠A are supplementary angles.
If the angles are supplementary there sum is equal to 180° i.e ∠A + ∠B = 180°
So, First we have to find the value of x. and then we can determine larger angle.
We know: ∠A + ∠B = 180
2x-30+4x=180
6x-30=180
6x=180+30
6x=210
x=210/6
x=35
So, value of x is x=35
Now finding ∠A and ∠B
∠A = (2x − 30)°
∠A = (2(35) − 30)°
∠A = (70 − 30)°
∠A =40°
and ∠B = 4x
∠B = 4(35)
∠B = 140°
So, we get ∠A =40° and ∠B = 140° and ∠B = 140° is measure of larger angle
I think you have to add all the numbers if im not mistaking.....hope this helped
