Answer: A
Step-by-step explanation:
Looking at the conditions, we can eliminate D. An isosceles triangle has 2 equal sides. 2 cm, 3 cm, 4 cm don't have 2 equal lengths.
We can next eliminate C. C is a right scalene triangle. Even if this is a scalene triangle, the key is the work "right". Any right triangle, regardless of it's angles, always fit the Pythagorean Theorem. C does not fit the Pythagorean Theorem.
2²+3²=4²
4+9=16
13≠16
We are left with the options A and B. A and B can both be correct answers, but it is the condition given in the problem that makes A the right answer. A states acute scalene triangle. That means there is at least 1 acute angle. Technically, B is also correct, but because the problem explicitly states 29°, that makes A the correct answer.
Answer:
The value of x in this case is 34°.
Step-by-step explanation:
Here, Lines TR and UP is intersecting lines at the point S.
⇒∠ TSU = ∠ PSR (VERTICALLY OPPOSITE ANGLES)
⇒ 4x = ∠ PSQ + ∠ QSR
= ∠ PSQ + 3x
⇒ ∠ PSQ = 4x - 3x = x
⇒ ∠ PSQ = x
Now, by The INTERIOR EXTERIOR ANGLES THEOREM In a TRIANGLE:
Sum of Two Interior angle of a triangle is equal to opposite exterior angle.
So, here in Δ PSR
∠ PSQ + ∠ SPQ = ∠ SQR
or, x + x = 68°
or, 2 x = 68°
⇒ x = 68/2 = 34°
Hence, the value of x in this case is 34°.
