The pH scale measures how acidic or basic a substance is. Lemon juice is said to have a pH of less than 4 and greater than 1.5.

Model the normal range of pH values of lemon juice, using a compound inequality.
1.5 > x > 4
1.5 < x < 4
1.5 ≤ x ≤ 4
1.5 ≥ x ≥ 4

Quadrilateral ABCD ​ is inscribed in a circle.
Lerok [7]
In general, the sum of the measures of the interior angles of a quadrilateral is 360. This is true for every quadrilateral. This does not help here, because there are two angles (angles B and D) we know nothing about. We only know about opposite angles A and C.

In this case, you can use another theorem.
Opposite angles of an inscribed quadrilateral are supplementary.

m<A + m<C = 180

3x + 6 + x + 2 = 180

4x + 8 = 180

4x = 172

x = 43

m<A = 3x + 6 = 3(43) + 6 = 135

Answer: 135 deg

Help&amp;EXPLAIN <br><br> Don’t use for points or will be reported and I’ll take the points back
anzhelika [568]

Answer:

X=151

Step-by-step explanation:

1. 61+90= 151

-Combine the two given angles

2.180-151= 29

-Subtract the total of the two combined from 180 because all 3 angles of a triangle add up to 180.

-29 is your difference which is also the angle next to X.

3.180-29= 151

-To find angle X you subtract 29 from 180 because angle X and 29 are supplementary angles that add up to 180.

-Therefore X=151
