In a right triangle, the measure of one acute angle is twice the sum of the measure of the other acute angle and 30. Find the me
asure of each acute angle in the triangle

Answer:
20, 70
Step-by-step explanation:
Let x = measure of first angle
then 2x + 30 = measure of second angle
The measures of the acute angles of a right triangle is 90.
So x + 2x + 30 = 90
3x + 30 = 90
3x = 60
x = 20
90 - 20 = 70
Answer:
Step-by-step explanation:
if we have a right triangle,
one angle=90
180-90=90
let x be one angle, and y another angle
the other is 2x+30
x+2x+30=90
3x=60
x=20
y=70

Step-by-step explanation:
7x + 3 = 3x + 35
4x + 3 = 35
4x = 32
x = 8
Answer:
7.39 ( nearest hundredth )
Step-by-step explanation:
Using the rule of logarithms
= n ⇔ x = 
Note that ln x represents
x
given 6 + ln x = 8 ( subtract 6 from both sides )
ln x = 2 ⇒ x =
≈ 7.39
Answer:
x > -7
Step-by-step explanation:
20 + 8 > -4x
Simplify
28 > -4x
Divide both sides by 4
-28/4 < x
-7 < x
x > -7
The answer is 8/3 but if your simplifying then the answer is 2 2/3 and if you want it in decimal form then the answer is 2.6 :)
