Answer:
m(BCD)=180°-m(BCA). In the triangle ABC m(BCA)=m(ABC)=(180-52)/2=64°. Finally, m(BCD)=180-64=116°
Step-by-step explanation:
Answer:
Step-by-step explanation: Let x be the smaller and y be the largest number.
Since x+y=13, we deduce y=13-x
Now, for the translation: "two more than the larger number" is y+2 , while "twice the smaller" is 2x
Their sum is y+2+2x
And since we know that y=13-x, we have y+2+2x=13-x+2+2=15+x
Starting off, if you understand the quadratic formula (if you don’t look up the formula) you’re looking for A,B, and C. A is 3, B is -4, and C is 11. You would then plug in these numbers following the quadratic formula, which results in;
The first option is the correct one. :)
Given :
A local company offers a monthly plan for 58.95 dollars.
The company is having a sale and offering a discount of 4.75 off the monthly plan.
To Find :
Sam says that the new cost is 11.45 explain Sam's error and find the correct new cost.
Solution :
Correct cost = Original price - Discount offered
Correct cost = $( 58.95 - 4.75 )
Correct cost = $54.2 .
Now, Sam's cost is $11.45 because he took $4.75 as $47.5 .
Hence, this is the required solution.
