Answer:
m∠A=90°, m∠B=60°, m∠C=30°
Step-by-step explanation:
step 1
Verify if the triangle ABC is a right triangle
Applying the Pythagoras theorem
----> is true
therefore
Is a right triangle
m∠A=90°
Find the measure of angle C
sin(C)=AB/BC
substitute
sin(C)=6/12=1/2
so
m∠C=30°
Find the measure of angle B
we know that
m∠C+m∠B=90°------> by complementary angles
so
m∠B=90°-30°=60°
I'm not sure about the formula.
But since 38/2=19
19-2=17
Linda is 17 years old.
a possible formula could be:
L=38/2-2
Answer: it would be B or C
Step-by-step explanation: Hope this helps :)
Answer:
6x + 2(−2x + 1) = 22
Step-by-step explanation:
6x + 2(−2x + 1) = 22
This step can be used to solve by substitution method.
Formula for the area of a circle is Pi*radius squared
So, we do Pi*2^2 which is 12.57
