The angle T1PT2 is 65-37=28 degree
use law of sine: sin37/PT2=sin28/7370, PT2=7370*sin37/sin28
Use a calcuator, I got the answer 9448
B. sin65=PA/PT2, PA=PT2*sin65=9448*sin65=8563
Measure of angle 1.
Angle ALS consists of angle 1 and 2. When you take the angle 2 away, subtract it, it ends with angle one.
Answer:
-4a + 16b -12c -12d
Step-by-step explanation:
Given: From 4a + 7b - 12c subtract 8a - 9b + 12d.
We are given two algebraic expression. We can add/subtract only the like terms.
(4a + 7b -12c) - (8a -9b +12d)
Now we have distribute the negative sign inside the second expression (8a -9b +12b). If we do, the sign changes.
4a + 7b -12c -8a + 9b -12d [Sign rule: -(-) = +; -(+) = -]
Now we can combine the like terms
= (4a - 8a) +(7b + 9b) -12c -12d
= -4a + 16b -12c -12d
Answer:
A. 25
Step-by-step explanation:
25 split into 5 groups, 5 in each of them.
There are 5 20's in 100 (the total)
25 = 5 + 5 + 5 + 5 + 5
I hope the explanation makes sense!
