Answer:
1. 3:1
2. also 3:1
Step-by-step explanation:
ratio has nothing to do with measurements
Answer:
The triangle has one solution. The remaining side c ≈ 4 and remaining angles B = 30°; C = 31°.
Option D is correct.
Step-by-step explanation:
if angle A is obtuse and if a > b then the triangle has one solution
We are given ∠ = 119° which is obtuse and side a= 7 and side b - 4 i.e 7>4 so, the triangle has one solution.
Finding remaining side c and ∠B and ∠C
Using Law of sines to find ∠B
a/sin A = b/sin B
7/sin 119° = 4/sin B
7 * sin B = 4 * sin 119
7*sin B = 4(0.874)
sin B = 3.496/7
B = sin^-1(0.4994)
B = 29.96 = 30°
We know that sum of angles of triangle = 180°
So, 180° = 119° + 30° +∠C
180° = 149° + ∠C
=> ∠C = 180° - 149°
∠C = 31°
Now finding c
b/sin B = c /sin C
4/Sin 30 = c/sin 31
4* sin 31 = c*sin 30
4*0.515 = c* 0.5
=> c = 4*0.515/0.5
c = 4.12 ≈ 4
So, Option D one solution; c ≈ 4; B = 30°; C = 31° is correct.
Given => ABCD is a rectangle.
Where AB(length) = 12.5 units
AD(breadth) = 2.5 units
Area of rectangle = length × breadth
= 12.5 × 2.5
= 31.25 unit²
Hope this helps!
Answer:
-7
Step-by-step explanation:
As x increases by 1, y decreases by 7, so the "rise"/"run" is ...
slope = rise/run = -7/1 = -7
