Answer:
b. about 63.9 units and 41.0 units
Step-by-step explanation:
In question ∠a= 29° and Side of a= 15 and b= 20
Using sine rule of congruence of triangle.
⇒ 
⇒ 
Using value of sin 29°
⇒ 
Cross multiplying both side.
⇒ Sin B= 
∴ B= 41°
Now, we have the degree for ∠B= 41°.
Next, lets find the ∠C
∵ we know the sum total of angle of triangle is 180°
∴∠A+∠B+∠C= 180°
⇒ 
subtracting both side by 70°
∴∠C= 110°
Now, again using the sine rule to find the side of c.
⇒
Using the value of sine and cross multiplying both side.
⇒ C= 
∴ Side C= 28.92.
Now, finding perimeter of angle of triangle
Perimeter of triangle= a+b+c
Perimeter of triangle= 
∴ Perimeter of triangle= 63.9 units

Step-by-step explanation:
The given equation is
The graph of the left hand side of this equation is
This quadratic graph has its vertex at (0,2) and turns upside down.
The right hand side of the equation is
This quadratic graph opens upwards and has its vertex at (0,-8).
The two graphs intersects at two points , which are (-2,0) and (2,0).
Answer:
(-0.3)^4 = 0.0081

Answer:
See below ~
Step-by-step explanation:
<u>X-intercept(s) : Take y = 0</u>
- 0 = x² - 2
- x = ±√2
- X-intercepts are : (-√2, 0) and (√2, 0)
<u>Y-intercept : Take x = 0</u>
- y = (0)² - 2
- y = -2
- Y-intercept is : (0, -2)
