Answer:e=-10
Step-by-step explanation:
-2e-7=13
-2e=20
e=-10
Answer:
4
Step-by-step explanation:
This is an isosceles and right triangle at the same time
In fact, this triangle is called 45-45-90 special right triangle and the side lengths for this special triangle is as follows:
The sides that see the angle with measure 45 is represented with x
and
The side that sees the angle with measure 90 is represented with x
one of the sides that has angle measure 45 is given as 4
to find the length of BC we we need to multiply 4
with
4
*
= 4
Answer:
(2, -4).
Step-by-step explanation:
x^2 - 4x
= (x - 2)^2 - 4.
So the vertex is at
(2, -4).
Answer:
The sine ratio is the ratio between the opposite side over hypotenuse. The cosecant ratio is the ratio between the hypotenuse over the opposite side, therefore cosecant is the reciprocal of sine.
To find a missing angle using sine, you would need to use the inverse of sine. For example, if the sine was
, to find the angle you would need to find sin⁻¹ of
which is x = sin⁻¹ (0.75). Therefore x equals approximately 49°.
Because ΔABC ≅ ΔHJK
AB = HJ (corr. sides, ≅ Δs)
HJ = 3.5cm
