9°

Step-by-step explanation:

In the given diagram we see that both the angles are complementary i.e. they form an angle of 90°

So therefore,

According to the question

$(6d + 8) + (3d + 1) = 90$

$= > 9d = 90 - 8 - 1$

$= > 9d = 81$

$= > d = \frac{81}{9}$

$= > d = 9$

Answer - d = 9°

Hope it helps you!!

Answer:

d is 9

Step-by-step explanation:

(6d+8) + (3d+1)=90

9d +9=90

9d=90-9

9d =81

d=81/9

d is 9

Prove by mathematical induction that 1+2+3+...+n= n(n+1)/2 please can someone help me with this ASAP. Thanks

Iteru [2.4K]

Let

$P(n):\ 1+2+\ldots+n = \dfrac{n(n+1)}{2}$

In order to prove this by induction, we first need to prove the base case, i.e. prove that P(1) is true:

$P(1):\ 1 = \dfrac{1\cdot 2}{2}=1$

So, the base case is ok. Now, we need to assume $P(n)$ and prove $P(n+1)$ .

$P(n+1)$ states that

$P(n+1):\ 1+2+\ldots+n+(n+1) = \dfrac{(n+1)(n+2)}{2}=\dfrac{n^2+3n+2}{2}$

Since we're assuming $P(n)$ , we can substitute the sum of the first n terms with their expression:

$\underbrace{1+2+\ldots+n}_{P(n)}+n+1 = \dfrac{n(n+1)}{2}+n+1=\dfrac{n(n+1)+2n+2}{2}=\dfrac{n^2+3n+2}{2}$

Which terminates the proof, since we showed that

$P(n+1):\ 1+2+\ldots+n+(n+1) =\dfrac{n^2+3n+2}{2}$

as required
