since line AB and CD make all right angles (given) angles 6+7+8 will equal 90 degrees.
According to the verticle angles rule:
angle 2 is equal to angle 6
angle 3 is equal to angle 7
angle 4 is equal to angle 8.
which proves that angle 2+4+7=90 degrees
Answer:
x = 50
Step-by-step explanation:
This is a ratio question and we are interested in calculating the value of x.
Let’s make the mixed fraction an improper fraction;
2 2/7 = 16/7
Thus;
16/7 : 0.6x = 4/21 :0.25
Removing the ratio sign;
16/7/0.6x = 4/21/0.25
16/0.42x = 4/5.25
Now cross multiply;
16 * 5.25 = 4 * 0.42x
84 = 1.68x
x = 84/1.68
x = 50
Answer:
y = 0.97
Step-by-step explanation:
y = 32x − 6
y = −92x + 21
Therefore: 32x − 6 = −92x + 21
124x = 27
x = (27/124), or 0.218
---
y = 32x − 6
y = 32*(27/124) − 6
y = 6.97
y = 0.97
====================
(0.218, 0.97)
