Answer: Isosceles
<u>Step-by-step explanation:</u>
Given: AB || DE , BC is a transversal
∠ABC ≅ ∠BCE by Alternate Interior Angles Theorem --> ∠BCE = 80°
∠DCA, ∠ACB, & ∠BCA are supplementary --> ∠ACB = 50°
By the Triangle Sum Theorem, ∠A+∠B+∠C = 180° --> ∠CAB = 50°
Triangle is isosceles because ∠A ≅ ∠C
Answer:
Option 1 is correct.
Step-by-step explanation:
Given two functions f(x)=sec x and g(x)=arcsin x
we have to find f(g(x)).
f(g(x))=sec(arcsinx)=sec A where A=arc(sinx)
As, A=arc(sinx)
⇒ 
⇒ P=x and H=1 gives 
hence, 
hence, 
Rationalizing, we get

Option 1 is correct.
Answer:
I believe that you multiply 5 x 10 because you multiply any of the terms by 5.
Step-by-step explanation:
Like another example is the 41st term which is 5 × 41 = 205
Answer:
True
Step-by-step explanation:
Well you use the same process really. Taking the individual numbers, lining them up and adding them. However, it is much more difficult because there is more to remember and you have to carry over more numbers. <span />
