I need to find x for this problem, in a category of geometry, help please!

sattari [20]

Answer:

Step-by-step explanation:

(7x)° + 61° = 180° (interior angle Postulate)

(7x)° = 180° - 61°

(7x)° =119°

7x = 119

$x = \frac{119}{7} \\ \\ \huge \red{ \boxed{x = 17}}$

When the factors of a trinomial are (x-p) and (x-q) then the constant term of the trinomial is:

Natali [406]

For this case, the trinomial sought is the following:
(x-p) * (x-q)
Rewriting we have:
x^2 -qx-px + (- p) * (- q)
x^2 - x (q + p) + (- p) * (- q)
Where we observe that the constant term is the one that does not depend on x
(-p) * (- q)
answer
D. The product of -p and -q

Solve this query plzzz

Olin [163]

Step-by-step explanation:

$\frac{\sin \:4A}{\cos \:2A} \times \frac{1 - \cos \:2A}{1 - \cos\:4A} = \tan \:A \\ \\ LHS = \frac{\sin \:4A}{\cos \:2A} \times \frac{1 - \cos \:2A}{1 - \cos\:4A} \\ \\ = \frac{2\sin \:2A.\cos \:2A}{\cos \:2A} \times \frac{1 - (2 { \cos}^{2}A - 1) }{1 - (2 { \cos}^{2}2A - 1) } \\ \\ = 2\sin \:2A \times \frac{1 - 2 { \cos}^{2}A + 1}{1 - 2 { \cos}^{2}2A + 1 } \\ \\ = 2\sin \:2A \times \frac{2- 2 { \cos}^{2}A }{2 - 2 { \cos}^{2}2A } \\ \\ = 2\sin \:2A \times \frac{2(1 - { \cos}^{2}A) }{2 (1- { \cos}^{2}2A) } \\ \\ = 2\sin \:2A \times \frac{1 - { \cos}^{2}A}{1- { \cos}^{2}2A } \\ \\ = 2\sin \:2A \times \frac{ { \sin}^{2}A}{{ \sin}^{2}2A } \\ \\ = 2 \times \frac{ { \sin}^{2}A}{{ \sin}2A } \\ \\ = 2 \times \frac{ { \sin}^{2}A}{{ 2\sin}A. \cos \: A } \\ \\ = \frac{ { \sin}A}{ \cos \: A } \\ \\ = tan \: A \\ \\ = RHS \\$
