Answer:
length of diagonals are BD = 33.039 cm and AC = 38.84 cm
Step-by-step explanation:
given,
sides of parallelogram is 20 cm and 30 cm
Angle between them is 80°. opposite angle of parallelogram are same the opposite angle is same.
other angle = 360° - 80° - 80° + 2 x = 200
x = 100°
Using cosine law
c² = a² + b² - 2ab cos γ
In ΔDAB
BD² = 30² + 20 ² - 2 × 30 × 20 cos 80°
BD = 33.039 cm
now in ΔADC
c² = a² + b² - 2ab cos γ
AC² = 20² + 30² - 2 × 30 × 20 cos 100°
AC = 38.84 cm
length of diagonals are BD = 33.039 cm and AC = 38.84 cm
I’m 85% sure it’s the long line on the bottom if not then uhm I guess I’m wrong
Answer:
10+15
Step-by-step explanation:
Answer:
The line you're looking for is parallel to y = 3x – 9, so it also has a slope of 3. Thus, you can rule out ... Here's what your work should look like: y = mx + b 0 = 3(–3) + b 0 = –9 + b 9 = b Now that you know both the slope and the y-intercept for this line, you can write the equation in the slope-intercept form: y = mx + b y = 3x + 9 The correct answer is Choice (C). What is the equation of a line that passes through the point (0, 3) and is perpendicular to y = 8x + 5? (F) y = 8x (G) y = 8x + 3 (H) (J)
Step-by-step explanation:
1)the letter x is two times the product two Hope fully this is hopeful and you can do the same on the rest by just changing the number
