Answer:
w=12
l=20
Step-by-step explanation:
The area can be found using the following equation:
Given the information provided, we are also told the following:
Therefore, we can plug in our length and our area:
We can solve by using the quadratic formula.
w=12, so w+8=20.
Answer:
4.4 cm
Step-by-step explanation:
To solve this problem, we have to remind the conversion factor between feet and cm. We know that:
1 foot = 12 inches
1 inches = 2.54 cm
So,
In this problem, Sarah's height right now is
h = 148 cm
She wants to be 5 feet tall by her next birthday: it means that her height should be
Therefore, she needs to grow by:
So, she needs to grow 4.4 cm more in order to be 5 feet tall.
Answer:
Add the two angles: 43° + 47° = 90°.
Step-by-step explanation:
A right triangle has an angle that equals 90°. Complementary angles equal 90°. Therefore, if you add these two angles, you will know whether or not △ABC is a right triangle. Triangle △ABC is broken up into two angles, m∠ABD and m∠DBC. When the measures m∠ABD and m∠DBC are added together, they equal 90°, and thus, form a complementary angle.
